This is like asking for my favorite song...impossible to answer. There are so many fun things to do!
car shows, air shows, art shows, paintball, putt putt, driving go carts, firing ranges, white water rafting, fishing, hiking, swimming, motorcycle rides, ziplining, wall climbing, dancing, movies at an outdoor ampitheater, zoos, museums, his favorite place that no one knows about that he wants to show only me...
