Lots of good information about the pma's at that link Boonie, thanks.  If I was in my 20's I would be all over it.   ;D  I've been to Raven Lake in the Mugwump pma back in 2009.  That lake gets some visitors every year and the trail wasn't difficult.  After watching some trip videos of other pma's I think I'll pass.  But if you have the energy and want solitude, that's where to go with the Canadian Border closed for now.
