I've seen this work well on other forums

Basically you post up a description of other harley riders you have passed or ridden along side on the open road (refrain from Rego plates or addresses).

EG (I'll start)

I rode with a CVO dyna up the Warby Highway to wandin the other night, rider was wearing a Brown Dainese jacket, sweet looking scoot for sure.

How was the Wandin meet Big Steve?

I was to busy to attend this one, hopefully there were less idiots there this time, doing burnouts in front.

I was riding through adelaide the other day and saw a terrific looking bloke wearing all black riding a fantastic black anniversary deuce. I was too stunned to signal this road going god. Then it hit me. I was looking at a reflection of myself in a window.
