I lived in Olney from 1971 to 1993.
I went through that "tunnel" (Drainage pipe) more times than I could remember.
Played on the tracks at the "Over and Under",stole pies from
Mrs.Smith's pies,and drank in the Tabor Junction!
Bought records at Getlin's and Sound Odyssey(they had DigDug in the back) and can remember going to Big Bill's w/
my family for dinner.
Climbed the roof at McDonald's,Rubin's Tower,and the trestles behind what's now the A plus on Mascher at Fisher.
I survived both Inky and Dougherty.
Does anyone remember "super Sunday" on Fifth Street ?
Pretty much a huge block party,with live music and vendors,etc.
