Nevada is in the migratory route for a huge number of bird species, especially raptors. If you grab a copy of Peterson, the binoculars and a picnic lunch, just drive somewhere. See what happens.

Kingman, the town, sucks. If you must go there, the Hualapai Mtn. Park is nice, even as early as April. Be careful where you walk. Lots of rattlesnakes.
