I've seen a few posts about this topic and Katherine from 5StarrScooters.com (be sure to notice the 2 Rs) called my attention this issue. My understanding of the situation is that certain cities in California, including San Clemente, are trying to ban scooters from skate parks because of the liability of potential injury. The reason why this isn't a concern with skateboarding and BMX is because those sports are on a list of activities deemed "hazardous recreational activities" (HRA). When a sport is on that list, the city's liability is limited with regard to injuries for individuals participating in that sport.
You can read more about it on the link below, but the short story is this: we need people in California to sign the petition to try to convince legislators to put scootering on the HRA list so that cities won't feel compelled to ban scooters from skate parks. Even if you don't live in California, you can still sign the petition to show your support. This could just as easily happen in other places as well, so let's help take care of this before it spreads any further.
You can find the petition and more information here: http://www.change.org/petitions/add-scootering-to-california-hazardous-recreational-list
Remember, if you live in California, you can always contact your local representative to make your voice heard as well. You can find your California state legislature representative here and PLEASE remember to be professional and respectful if you want to help our sport and our cause. Being rude and vulgar only gives them more reason to ban scootering. Show them that scooter riders are good people.
If you still aren't convinced, here's another article from Inside Scooters about the topic: Petition to Remove Scooter Ban at San Clemente Skatepark
Thanks for taking the time to read this. Please do what you can to help.
