We have PAVE PAWS out here too (lucky us!).  Though I haven't had any problems from it, I've always wondered if we'd be trading one problem for another...  If the uplink were on 70cm, would we be in violation of the power restrictions when we transmit?  Many of the 70cm repeaters here are either off the air or turned down so far as to almost not be worth having.

Personally, I've got some serious hillage between my QTH (CM98kx) and most of the valley, but Google Maps indicates there's a nice little canyon dropping down the hill directly in the direction of the AF base.  Makes me nervous on those low passes to the North West.
