August 6, Angeles Crest 100 (signed up)
August 20, Waldo 100K (lottery Feb 15-24)

I got into Zane Grey and put in for Western States. Maybe because I've been traveling to dreary London for work and not running, I'm not looking forward to many races, but there's time for that to change.
This new 50K in Mendocino sounds really nice, but conflicts with Zane Grey.
US Skyrunning lists a Tahoe-area 50K June 19 that could be great.
BF reminded that the Idaho Trail Ultra Series puts on some good races (two 100K and a 50M in June, July, and August) that could justify a trip. I'm disinclined at the moment, but after Western States and Hardrock lotteries don't pan out, and if Capitol Reef doesn't put on a 100, I could swing that way for sure. There are nonstops on Southwest from Oakland to Boise, after all.
