While most GA/GI events begin at 6 pm, you can come early, and enjoy making sidewalk chalk art from Noon to 6 pm at BFG Cafe, 5335 Penn Avenue. Colorful fun for all ages! And The Pittsburgh Glass Center @5472 Penn is open where you'll see a world-class exhibition of work by international glass artist, Eunsuh Choi...but hold on to those kids :-).
