I used my Rig 500 on my LA Weekend Ride for the first time and it attracted quite a bit of attention. I was the only one with "no sucking" mouth piece and I am sure fellow riders will not want to "suck" anymore, too. You dont know that you need/want something until you see it. That is what happened with the other riders. When one of them needed water to clean his muddy goggle, I was there to help with my Rig 500. It is not a high pressure car washer but it does the job... I am sure we will see many more Rigs around pretty soon... E.S.
