I can usually spot a newbie in two seconds once they are on the water. I need help telling if some one has a clue on the beach, and thats where questions need to be asked.
It would be nice to have some indicator out on the water that a rider not only can go upwind, but they understend right of way or they're not going to jump right in front of you.
I'm kind of cheap so I was thinking of using extra wide colored rubber bands they are cheaper than armstong type and they don't have them on the counter at the gas station.
