Have an awesome trip down there! We launch dec. 18th next year, so would love to hear about it. Sounds like you should have great water like mike said, with the high power demand.
Kinda off topic, but have been taking a hot tent on winter trips recently, has been awesome!
Mine is an 8 man from seek outside, with the large size wood stove, just took it on west water, and it made a world of difference! Hang out/ go to sleep in a warm place, wake up and restart fire before you get up, warm, dry gear to put on in morning, was worth every penny.
Thought i'd share, more gear to buy, but might be a worth while group expence, think our low's this weekend were in low to mid 20's, average low's at phantom should be warmer then that, which makes me happy.
