Boy, this is a tough crowd on this thread.
I am a seasonal site camper and we use our golf cart every day we are there. Could I get along without it sure, but I too like a toy and also for practical reasons.
I use the fold down back seat to haul my fire wood from my truck to my wood pile for my camp fires. I will also take the cart to the camp store or resturant that is at the front of our 130 acre campground. The store opens at 7am and I am sure those that camp around me would rather not hear my electric cart than the truck fire up and roll past on my way for coffee.
If you have teenage children (14 & 19 boys here) the cart is one more thing for them to do and is a big draw for them as they cruise around looking for your daughters.
The campground also sponsors poker runs, parades ect. That we enjoy participating in.
Like I said, tough crowd, if we rode horses, you would complain about the waste they drop in front of your trailer.
