ComedySportz Improv Theatre Richmond did a great YA program for us last night, with a 30-second (then 15, then 7...) version of Harry Potter and the Sorcerer 's Stone, a sound symphony, "What are you doing?" and other wacky improv games. The 50 teens (and 7 or 9 adults and tots who snuck in) enjoyed it, and -- oh yeah! -- that's about twice as many people as the other area libraries got!! Not that it's a contest.
