Whoa WonderlandPark, you're one of us older forumers? Yippee, another mature member.
There have been quite a few changes in Ithaca since the 70s. The old Woolworths bldg is now the county library. The big structure next to it is a 700 car parking garage. A midrise condo building is to be built behind the garage next to six mile creek. The green street parking garage is going to be partially dismantled, and the the helix and bridge over Green st will be removed to make way for a new mid rise office/apartment building with retail and multi screen theatre complex. At the intersection of Seneca and Tioga, a new office bldg/Hilton hotel has been built.
Which school did you go to, Cornell or IC? Whichever, you probably wouldn't recognize Collegetown:
Anyway, always nice to have another person who knows the natural beauty (if bad weather) of Ithaca.
