Kelso & Trigger on the road again

Can you tell I've become friends with everybody at my Physical Therapy office? They let Kelso & Trigger try out the Anti-Gravity machine. It's amazing - it pumps air into a chamber to counteract gravity. It “unweights” a user by up to 80% and so reduces the impact of walking or running on both muscles and joints. Kelso & Trigger loved it - if you look at the top of the vertical photo, they are watching themselves on the screen.
