Question: What was Rocket Row?
About the article "National Air and Space Museum", section "History".

Candidate passages:
The pendulum rocket fallacy is a common fundamental misunderstanding of the mechanics of rocket flight and how rockets remain on a stable trajectory.
The first liquid-fuel rocket, constructed by Robert Goddard in 1926, differed significantly from modern rockets in that the rocket engine was at the top and the fuel tank at the bottom of the rocket.
It was believed that, in flight, the rocket would "hang" from the engine like a pendulum from a pivot, and the weight of the fuel tank would be all that was needed to keep the rocket flying straight up.
This belief is incorrect—such a rocket will turn and crash into the ground soon after launch, and this is what happened to Goddard's rocket.
Use of basic Newtonian mechanics shows that Goddard's rocket is just as unstable as when the engine is mounted below the fuel tank, as in most modern rockets. 
Haas is a family of rocket space launchers developed by ARCA for the Google Lunar X Prize competition and for their national manned space program.
It consists of Haas balloon-launched orbital rocket, Haas 2 airplane-launched orbital rocket, Haas 2b ground-launched suborbital rocket and Super Haas ground-launched orbital rocket.
It was named after Conrad Haas, a medieval rocket pioneer who lived and worked in what is now Romania, and was the first person to describe a multistage rocket in writing. 
Hair Rocket is an indie rock band from Philadelphia, Pennsylvania.
Hair Rocket was formed in 2008 by former Aderbat musician Chris Blasucci and pumps out what it calls "enlightenment through cathartic art".
Their slogan is “We cut, We light, and We release”. 
The NATIV rocket was a North American Aviation-designed launch vehicle.

As of 2012, three Pennsylvania state parks are also the site of ski areas run by private contractors: Big Pocono (Ski Camelback), Blue Knob (Ski Blue Knob), and Denton Hill (Ski Denton).
(Two other state parks had commercial ski operations in the past Laurel Mountain (from 1939 to 2005) and Black Moshannon (from 1965 to 1982).)
Two parks are operated by other governmental bodies: Hillman (managed for hunting by the Pennsylvania Game Commission) and Norristown Farm (operated by the Montgomery County Department of Parks).
Three parks are operated by other organizations: Susquehanna (operated by the Williamsport/Lycoming Chamber of Commerce), Prompton (operated by non-profit "Friends of Prompton"), and Salt Springs (operated by non-profit "Friends of Salt Springs").
b.
The Pennsylvania counties without state parks as of 2012 are: Armstrong, Juniata, Lehigh, Montour, Snyder, and Wyoming counties.
Two of these counties are sites of former state parks: Crooked Creek in Armstrong County, and Snyder-Middleswarth in Snyder County.
c. The goal of having a state park within 25 miles (40 km) of every resident was set by Maurice K. Goddard (Secretary of the Pennsylvania Department of Forests and Waters, and then of the Department of Environmental Resources from 1955 to 1979).
d. The seven National Natural Landmarks at least partly within current state parks (with the park name in parentheses, if different) are: Cook Forest, Ferncliff Peninsula (Ohiopyle), the Glens Natural Area (Ricketts Glen), Hickory Run Boulder Field (Hickory Run), McConnells Mill, the Pine Creek Gorge (includes Colton Point and Leonard Harrison), and Presque Isle.
One National Natural Landmark, Snyder Middleswarth Natural Area, is a former state park.
e. The date of establishment for many Pennsylvania state parks is not always clear, especially for parks developed from state forest property.
As an example, consider Upper Pine Bottom, which, as of 2012, is a picnic area surrounded by Tiadaghton State Forest.
These state forest lands were acquired by the state by the early 1900s, the site was "Upper Pine Bottom Class B Public Campground" by 1924, the CCC built a pavilion there in 1936 (which is no longer extant), but it was not officially transferred from the Bureau of Forests to State Parks until 1962. f. This park was one of twenty-one chosen by the Pennsylvania Bureau of Parks for its "Twenty Must-See Pennsylvania State Parks" list.
g. This park has one or more historic sites or districts on the National Register of Historic Places.
h. There have been a considerable number of changes in Pennsylvania's categorization of its state parks and other protected areas over the years, so that what can be called a former state park is not always clear.
This can be seen by comparing the following three lists from 1923, 1924, and 1937.
<br>In 1937, the state published a brochure listing the following forty-nine protected areas: six State Parks (Caledonia, Childs, Cook Forest, Presque Isle, Pymatuning, and Ralph Stover); eight State Monuments (Bushy Run, Conrad Weiser, Drake Well, Fort Necessity, Fort Washington, James Buchanan, Valley Forge, and Washington Crossing); ten Forest Recreational Reserves (Clear Creek, Colton Point, Cowans Gap, Kooser Lake, Parker Dam, Pecks Pond, Promised Land Lake, Snow Hill, Whipple Dam, Whirl's End); sixteen Wayside Areas (Big Spring, Black Moshannon, Cherry Spring, Colerain, Greenwood Furnace, Halfway (now R.B.
Winter), Joyce Kilmer, Kettle Creek, Mont Alto, Pine Grove Furnace, Reeds Gap, S.B.
Elliott, Sideling Hill, Sizerville, and Tea Spring); seven Forest Monuments (Alan Seeger, Bear Meadows, Ole Bull, Detweiler Run, McConnell Narrows, Mount Logan, and Snyder-Middleswarth); and three State Forest Lookouts (Leonard Harrison, Martins Hill, and Mount Riansares).
<br>Only twelve of the twenty-six public campgrounds from 1924 are on the 1937 list.
Of the forty-nine areas on the 1937 list, twenty-eight are state parks as of 2012, while nine are former state parks, and twelve are in state forests (eight of these still retain their names as state forest picnic, natural or wild areas).
