Good info bwodom .
My wife and I will be hosting and volunteering when we retire in 3 years or so.
We were Crater Lake Ski Patrollers. It is a volunteer position. I did 12 years. My wife did just a few. If it wasn't for the Ski Patrol, winter would not be a very safe time at Crater Lake. We had to have written instruction on our job description so that we did no get railroaded into doing the Rangers odd jobs.
It was fun, interesting, necessary, sometimes dangerous and sometimes real work. I saved a few lives and also did some major first aid.
The budget is zero most of the time unless it can be documented as necessary. Going through the loops can make things happen. Asking the right question can help too.
