I would recommend going to Ryan airfield. You have to contact the RAF to receive an airstrip safety briefing prior to landing there. Go to there website and find some contact info. http://www.theraf.org
and get permission. It is located at West Glacier and they have great camping facilities and a courtesy car.
There are many courtesy cars in the area. There are three in Polson; great for a grocery run and fuel, Seeley Lake; great for a Lindey's Steak House meal, and more located at Ronan and St. Ignatius. I'm not sure what is available in Kalispell, etc.. It is FREE to use them, just replenish the fuel supply...
Polson airport also has a room for rent with a full kitchen,etc. for pilots. I don't know exactly what the price is but I want to say $50/night.
Schafer is surely the preferred camping. It has bear boxes for food and water right at the camp grounds.
I had originally thought that I would find a place with a courtesy car so I wouldn't have to rent one. But I didn't know if they would appreciate the car being gone all day. Also, if only one was available, I couldn't take the chance that it wouldn't be available, so I decided a rental was the better way to go. I know of Polson, and that was the original plan, but that would be a long day of driving just to get to and from the park. That is good to know about the room there though, thanks.
I probably should have given Kalispell (S27) a closer look, but none of my searches for car rentals would bring it up as a rental location, even though the AOPA directory says that 4 different agencies rent out of there. For now fuel shows to be cheaper at GPI than S27...we'll see if it holds. Regardless, I imagine we'll top off else where.
Thanks for the info on Ryan. I had seen the video on the RAF site. I didn't know about the breifing though, so that is good to know. Had I not already secured a car at GPI, I might even be tempted to gamble on their car being available. Regardless, I'd still like to check it out.
Again, thank you to you all for the input. John, thanks for checking on the fuel over at Cabin Creek.
