While on vacation we had the opportunity to go to a demonstration on bats. I call them rats with wings but apperantly bat houses are popular in Michigan. He was explaning that bats eat 6,000 bugs per hour. I guess that could be usefull. The boys thought they were great. They listened to the man explain and then waited in line to see the bats up close. JJ wants one for a pet. Ewwwwww!!!
