Hotel Cadillac Rochester New York 1939- every time we're in ROC we drive by this. It doesn't look anything like this now. It looks like the place Tom Hanks stays at in the movie Big. For that reason alone I love it.
The Science Center is another great stop within Forest Park. This Free mostly museum has many interactive exhibits. It also features many paid exhibits if you choose. FYI the IMAX is not Free, but you knew that.
