Lived in Wheaton, MD right across Wheaton High School, until I was six, then moved into a newer community in Rockville, off Bauer Drive, until I left for the Navy in 1983. My sister, my brother, and I all graduated in different High Schools: my sister at Wheaton HS, my brother at Rockville HS, and I graduated in 1982 at Peary HS (now a Hebrew Academy. Never realized how large a Jewish community we have there).
Rockville at that time had a population of around 30,000-35,000. Now it's upwards of 62,000. The place is so crowded now. The Pike is so congested and so built up. I would never move back there again. My parents bought the house new for about $30,000 in 1969, sold it for $180,000 in 1996. But identical homes were priced at $500,000 at the peak of the housing market.
My friends and I used to hang out at Aspen Hill, White Flint, LakeForest, or Wheaton Plaza back in the day. We'd also take frequent trips to Great Falls out on River Road and explore the caves and climb the rocks. Good times.
