My $0.02 worth is that while I agree that walking all over a show site the size RPRU needs is very hard on many older people's feet/legs (mine included), and golf carts are profitable for the hosting club, once the carts are away from the rental area it's almost impossible to police the way people use/abuse them. Opening up the use of 4-wheelers, CC's & trailers except for parade purposes really puts people walking in jeopardy. At RPRU in Madison, SON I took the '51 M, it had the shiniest paint. We parked in the display field, but took the M into the show grounds to see some sites and be seen, and save a LOT of walking. But running a full size tractor around ended up being actually slower than walking because of all the golf carts running ALL over. We parked the tractor after 30-40 minutes.
Like Tom says, nothing like people NOT watching where they're going to cause problems. I remember visiting Brookfield Zoo in Chicago when I was about 12-14 yrs old and having a dozen unattentive parents run me over with BABY strollers. Same thing at amusement parks & tractor shows. If the kid can't walk and hold on to Mom or Dad's hand, let the kid stay with Grandma, She'd LOVE to spoil the kid for the day!
And mis-use of vehicles like golf carts, etc at shows is common. Buddy & I went to the second "Half Century of Progress" in '05. Several tractors left the show grounds headed for the plowing demonstration field. The mass of golf carts took off, My Buddy & I walked. When we got there several tractors had already set off across the field. A CASE # 1030 tractor with M&W turbo pulled up to sink his semi-mounted 5-16" plow in and show off. As soon as the first 2-3 bottoms got in the ground, which was about as hard as concrete, he spun-out, hit the 3-point lever to shallow the plow up which caused the frt end of the tractor to come up about FOUR-FIVE feet. There were golf carts & 4-wheelers sitting within 8-10 feet of this tractor. I grabbed my Buddy and said, "Lets get out of here before someone gets KILLED!".
I guess the problem with RPRU's is it's suffering from their SUCCESS. They're SO big anymore it takes miles of walking over two-three days to see everything. This problem of pedestrians vs golf carts, 4-wheelers, CC & trailers is a tough one. Too bad the insurance companies will probably decide the situation for us all.
