ticking off the South Nahanni this year; maybe try the Snake (in Yukon) after that - that about empties my bucket, but will most likely do Yukon R again, and Allagash again as well.

doing the Current, Jacks's Fork and ? in MO in a couple of weeks, so can scratch those off - still leaves a trip on the Buffalo in AR to do

just got back from a rim to rim to rim backpack in Grand Canyon - 44.5 mi and 10,300 feet elevation gain in 4 days - may do that one again too, if I take enough stupid pills;  did raft the first 88 miles of the river 3 years ago on a private trip - might consider doing a commercial trip thru the bottom "1/2" some day

only other things on my bucket list would be another climbing trip to Yosemite, but I'd have to find better partner for that I think.  and maybe a caribou hunt someday  -  both of these aren't too likely to happen, but who knows
