The view of Public Square as seen from the Terminal Tower observation deck.

The Terminal Tower observation deck opened once again to the public over the weekend, but nabbing a ticket isn't the easiest thing to do in Cleveland.The tours are only available on Saturday and Sundays, and tourists must first sign up for the pleasure of experiencing this bird's-eye-view located on the 42nd floor of the 52-floor building. This $5 tour is self-guided, and guests are asked to limit their viewing time to 25 minutes. No walk-up ticket sales are accepted, and signup times only run from noon to 3:30 p.m.On a clear day, not that anyone can guarantee such a thing during spring in Ohio, observers can see for 30 miles in every direction.Sign up for a tour date and time now through May 26 right here.
