La Salle Senior High School was a multi-story Post-Modern era high school in Niagara Falls, New York built in 1956 and was run by the Niagara Falls City School District.  It was closed in 2000 and was subsequently merged with the "old" Niagara Falls High School to create the "new" Niagara Falls High School due to declining student enrollment associated with the declining population of Niagara Falls.  It is not to be confused with the former La Salle Junior High School, which is now the La Salle Preparatory School, also located in Niagara Falls.  The school was razed in 2001 to eventually make way for a Wal-Mart and the associated plaza buildings that include a Hobby Lobby and which also includes a Sam's Club, both located on what was once sports fields and viewing stands.  The school was located at the eastern front end of the large property and on prime real estate on Military Road almost directly opposite Wegmans, which is a busy shopping corridor which also includes the expanding Fashion Outlets Mall.  The school's nickname was the "Explorers", which is now being used by the preparatory school.  The site had once been farmers fields, with the Star-Lite Drive-In also nearby. Aurora, Colorado counts among the 60 largest cities in the United States, with a population greater than such cities as Pittsburgh, Buffalo or Salt Lake City, but lacks a skyline typical of cities its size.  This is due to Aurora’s largely suburban character and relatively small central business district.  Indeed, “Original Aurora”, the city’s traditional downtown, has only one building of notable height.  During Aurora’s most intense period of growth in the 1970s and 1980s, the area in the geographic center of the city near the I-225 freeway and Aurora Mall (now Aurora Town Center) was envisioned as “Aurora City Center”, a new downtown complete with a collection of tall office buildings.  However, these plans have yet to materialize and a large tract of undeveloped land still lies east of Aurora Town Center.  As is typical of suburban development patterns of the postwar era, Aurora’s tallest buildings are located along the I-225 corridor, largely either in the vicinity of the Parker Road interchange in the southwestern portion of the city, or near the Colfax Avenue interchange in the northwestern portion of the city, where a large medical services and research campus has emerged.  In recent years, a number of hotel properties have also been built in Aurora along I-70 in the environs of Denver International Airport (DIA).
