I wish that I could, but considering that I'm abandoning...err...leaving my kids for 8-13 days (depending on whether I fly back from Atlantic City) in June to crew RAAM, it's going to have to be one or the other. I'm leaning toward Eastern Sierra. I was worried about doing 10,000 feet of climbing, but I recently did a 112 mile 10,500 ft ride (Encinitas to Palomar Mountain observatory and back) and felt really strong most of the day. I'm thinking that if I can handle the 8500 feet of climbing on the Butterfield DC, that ES shouldn't be too bad.
