If you like bats, I have a vacation for you. Head out to New Mexico and visit the Carlsbad Caverns National Park. It includes 116 caves, some of the largest in North America. There are a variety of tours from self-guided to crawling through narrow passages. The park also offers great scenery, camping and hiking, of which Joey Z does none. The one thing you can't miss is the daily bat exodus in the summer months. Each day at sunset, nearly 400,000 Mexican bats exit the caverns to feed at night. If you are heading out West consider a stop at Carlsbad Caverns.
P.S. Tell Batman Joey Z says Hello.
