Insurance

Hi All, My name is Francesco,I'm italian. Me and my girlfriend are going to have a  50 days on the road climbing trip around south California, in November. I'm trying to get an appropriate health insurance that covers also eventual problems coming from climbing practice, and seems that it does not exist. Let me better explain: We're going to spend 3 months in California, and of course we've to stipulate a Health Insurance for any evenience. Being the sport activity the hearth of our trip (Climbing, Surfing, Running) we would like to be insured also during sport practice, and here comes the problem: All the on-line insurance I've checked do not guarantee their insurance during climbing, so as our insurance brooker. So, here is my question: how did you guys solve this problem? Is there any specific insurance which covers also climbing?  How does it works in case of being in needs of medical support after a problem resulting from climbing? Thanks and Enjoy! Cisko
