I also attended the improv show at Geva Theatre; http://www.zvents.com/rochester_ny/events/show/147364465-geva-comedy-improv-zombie-horror-show called Zombie Apocalypse Saturday evening. It was a good show but I thought a lot more could have been done from a comedy perspective and given the topic. However; there was vomit, blood spray, machine guns, Zombies and more! I really wanted my picture taken with a zombie but there wasn't an opportunity.
Below are pictures of both events.
