I should probably give Center Hill a try anyway. all my favorite spots
at Priest are bone dry this time of year anyway.

As far as the mounting thing, I have used the rubber mounts in the
past, but they degrade pretty fast and I was always having to tighten
them. Now, I use through bolts and large fender washers with a nylock
nut on the bottom. If you have access to the underside of the deck
this method is very solid and cheaper too.
