Great vacation! But you're are right - it was COLD - at least for camping. Nights were in the low 20s and we had to unhook at night to keep the water from freezing. The area around Bend, OR is called "high desert" and is covered with ponderosa pine with some sage brush underneath. The drive home - 400 miles was spectacular- even drove through a small blizzard on one of the passes. The Columbia River Gorge is a site to see!!
Fish did just fine all alone. I just tossed some of those 5 or 7 day feeding tablets in - haven't even checked yet to see if they ate them or they dissolved or whatever they do.
