Penobscot Knob: Penobscot Knob, also Penobscot Mountain, is a summit located in the western fringe of the Poconos nearest to Mountain Top, Pennsylvania which in the Solomon Gap pass below it lies an important multi-modal transportation corridor.  At one time before incorporation, Mountain Top and the saddle of the pass was known by the Amerindian name Penobscot.  Penobscot Mountain forms part of the drainage divide between the Lehigh Valley & greater Delaware River drainage basin and the Wyoming and Susquehanna Valley, part of the Potomac River drainage basin.  The pass formed between Penobscot and Haystack Mountain a few thousand feet to the West was one of the few places a railroad could be envisioned in the 1830s when the fuel crises in eastern cities demanded easier transportation to the Northern Anthracite Coal Fields, which ironically, came to be exploited by the company with a near monopoly in providing coal from the Southern Anthracite region, Lehigh Coal & Navigation Company (LC&N, f.1821), which had built both the Lehigh Canal, but also the nation's second railway, the Summit Hill & Mauch Chunk Railroad.  The whole uplands north and west faces over look the Wyoming Valley from the southeastern corner near Hazleton towards and through the greater south Wilkes-Barre area.  The southern and eastern slopes just give peeks into portions of the Poconos and wider views of the Lehigh Valley descending down to White Haven, for the Poconos technically are left-bank bounded by the Lehigh.

Valley International Airport: Valley International Airport (VIA) (IATA: HRL, ICAO: KHRL, FAA LID: HRL) is owned by the City of Harlingen, in Cameron County, Texas.  Valley International Airport is operated by a nine member airport board appointed by the Mayor.  HRL is centrally located in the Rio Grande Valley (RGV) making it a logical choice for travel to the area.  Valley International is often referred to as the “Gateway to South Padre Island” with travel amenities that provide door to door transportation to South Padre Island.  With over 2,400 acres HRL is the largest airport in the RGV with room and resources to meet future airline expansion needs.  HRL also provides the longest runways in the area with modern aircraft approach systems that minimize chances of travel delays during inclement weather.

Pennsylvania Route 987: Pennsylvania Route 987 (PA 987) is a state highway in the U.S. state of Pennsylvania, running 10.3 mi from U.S. Route 22 (US 22) near the Lehigh Valley International Airport north of Allentown north to PA 946 in Klecknersville.  The route begins at a cloverleaf interchange with the US 22 freeway north of Allentown in Lehigh County and heads to the east of the airport as a four-lane divided highway called Airport Road as it crosses into Northampton County.  PA 987 narrows to a two-lane undivided road and continues north, becoming concurrent with PA 329 as it heads into Bath.  Here, PA 329 ends and PA 987 briefly runs concurrent with PA 248 before leaving the borough.  PA 987 continues northwest and serves Chapman before ending at PA 946.  PA 987 was first designated in the 1930s between US 22 (Union Boulevard) in Allentown and PA 946 in Klecknersville.  After US 22 was relocated to its present freeway alignment in 1955, the southern terminus of PA 987 was cut back to its interchange with US 22, which used to carry Interstate 78 (I-78) as well.  In the early 2000s, PA 987 was widened into a divided highway and shifted to a new alignment near the Lehigh Valley International Airport.

Lehigh and Mahanoy Railroad: The Lehigh and Mahanoy Railroad, originally the Quakake Railroad (pronounced quake-ache), was an independently financed railroad planned and built at almost the same time as the Lehigh Valley Railroad (LVRR), when in part, some of its backers were also of the backers (and perhaps officers) of the Lehigh Valley Railroad.  The railroad is mentioned as part of the engineering report following the survey of 1846 by Robert H. Sayre, at the time chief engineer of the Lehigh Coal & Navigation Company, where the branch is "described as part of the overall scheme to connect New York Harbor via the Central Railroad of New Jersey to the frontiers via Lake Erie and the Susquehanna River valley.  The official incorporated name on the report is the Delaware, Lehigh, Schuylkill, & Susquehanna Railroad Co. where the Schuylkill name is the Quakake Creek climb out of the Lehigh Valley and drop down into Delano Junction which has a descent path to Tamaqua, Pennsylvania in the Little Schuylkill River basin.  Accordingly, the Quakake Railroad would become part of the Mahanoy Branch of the Lehigh Valley Railroad in northeastern to north-central Pennsylvania.  The Catawissa region was an important source of iron ores and developed into an Anthracite pig iron smelting center, as did Catasauqua, Pennsylvania also on the line of the Lehigh Valley.
