I am one of those "slowpokes" everyone complains about.
One incident comes to mind from reading these posts. I was driving back to my site and there was a wide section of campground road between the playground and the seasonal sites. There was a large dump truck parked on the gravel next to the road. Two red flags in my mind, playground with kids and blocked view from dump truck about 10 feet to the side, so I slowed a little more below the 10MPH campground limit. Sure enough, a boy about 10 years old ran out from behind the dump truck. I hit the brakes hard. The boy's eyes got big as he saw me. I was relieved that I was still several feet away from him when he realized I was there and I was stopped.
I will continue to be a "slowpoke" and I don't care who is behind me, even if it is the campground staff in their golf carts.
