1. Two person tarps are especially nice in the PNW for 1 person, with the rain and all. I wouldn't use a solo tarp around here in today's weather!
2. Ron's (MLD) two person spinnaker tarp is almost identical to the Spinntwin, I think. Ultimately, the choice is between Spinnaker and Sil-nylon. Sil is cheaper, spinnaker stays more taught (and therefore less fuss, I find)
3. Charburger, underneath Bridge of the Gods in Cascade Locks, is the requisite stop after anything done in the Gorge-related between Portland and before Hood River.
