Just a start

Hi Everyone, I've spoke to most of you about trying to get a resource page up and running for ski patrol. I've started down the road and here is where we are at currently. I'd like us to use this page a community builder and resource for those involved in the patrol. To do that I envision posting our mountain forecast, avalanche control start times, and pit profiles if possible, along with other current events. Any input before we start spreading the word to the whole patrol? John Schaefer
