Having been the embarrassed noob at the ramp before, I do try and help when I can. But only after getting all the entertainment value out of it! Twice this year I have helped people out. Once was a guy with a jet ski trailer who just could not keep from jack knifing it. After he was totally red and cussing so loud you could hear it on the water I asked him if I could back it up for him. The show him how to get them off, then where to park.
The other time I had to winch a guy up the ramp after he somehow got his trailer in the water but his truck stuck in the grass next to it. Still can't figure that one out.
