Well, ya never know. With the great late season snow last year for example, the lakes basin was still closed well into June meaning any campsites reserved there had to be canceled. During the drought years early June was a good time to fish. Shady Rest in town (as you know) should be open and has a group site area. Or, depending on how many people and how much they want to spend you could always rent a condo or two? There will always be someplace to fish then no matter what. Well, I shouldn't say no matter what since the town does sit on a volcano, but you know what I mean.
