We have your garden variety vacuum sealed salmon available at the more 'boutique' grocers in town, but I couldn't tell you much in regard to quality, wouldn't know the difference. I had plenty of quality salmon when I was younger living in the Olympic Penninsula, but what does a punk kid know?
I'm checking into campsites at Mathers, each site looks like they allow up to 6 individuals, 3 tents, and 2 vehicles so we should only need to reserve one or two sites. I will check into reserving a site near Rob Lee's site #162.
You're the man! Looking forward to meeting you out there and I appreciate you're generosity and willingness to hang around with a band of strangers. I haven't been down to the Colorado River so I'm with you in being a GC newbie that's looking to spread some wings.
