With gas prices on the rise, its the perfect time to take a look at the attractions right in our own backyards. This weekend, an event will do just that. Its the annual One Tank Travel Expo. It will feature everything from the beaches of Presque Isle State Park, to Pittsburgh area amusement parks and New York State wineries. The criteria for the event is that you must be able to get there on one tank of gas. Its taking place this Sunday at the concourse of Union Station. It runs from 12 noon to 4 pm. Admission is just one dollar and benefits the Summer Festival of the Arts.
