My nephews son could hardly climb in the 37 when I started it back in 95. Today at 13 he loves old cars and trucks and helps his dad and me all the time. I also have a 5 year old grandson that dearly loves to get into things in the shop and loves riding in the 37. I currently have a 52panel to restore so I'm sure he will have a big part in it! My 23 year old daughter still loves to ride in the 37 she remembers scrapping mud and grease off of but school has kept her out of the shop for sometime even thought she does come and hang out with dad when she can!
