PS. I am doing the gas, and we been doing this for about 3 years. And don't think it's unsafe not wearing a helmet.. Most of us grew up jumping from seat to seat all through our youth, and we are here. live a little which you see we are..:) Sorry I see grown ups on the beach wearing a helmet riding their bicycles I shake my head and say to (myself) man I'm glad thats not me..:)
