Northern Idaho/Priest Lake cruising?

You know how sometimes an idea pops in your head and you just have to chase it down? This week I've been considering taking Marianita on a several hour road trip across Washington State to Priest Lake. It gets mentioned now and then as a nice place and there are even a few YouTube videos of trailer-sailor types doing a bit of camp cruising. I'm thinking it might be nice to get away from the tides and currents of the Salish to lake sail for a week this summer. 2400 feet high and not too far from the Canadian border so it definitely has a May-September seasonality. Based on the fishing map I found (no NOAA charts as far as I can tell) it sure looks inviting, there are some boat-in campsites and what look to be plenty of spots to anchor out. 19 miles long, 4.4 wide so not too big but plenty of room for a small sailboat to putter around.
I've just started reaching out to see about storing the tow vehicle and trailer...one of the resort/marinas up here ought to have parking. Anybody been there? Heard good or bad things?

If you would have a good boat, be a good guy when you build her - honest, careful, patient, strong.
