Drop the kids off at Frog Hall (2114 Hayes Street) for a Kids Play Night!  While you have an adults-only night out on the town your kids will meet lizards, frogs, snakes and tortoises; do fun and creative hands-on science and art projects; munch on pizza and healthy snacks; and watch a movie.  Good for 2 children, ages 4 and up, any Saturday night from 5:30 to 9 PM.  Expires March 1, 2010.
