After two weeks with Betsy wandering around the Sierra and introducing her to places she hadn't seen (the west side in particular), she flew home to the real job and I settled on doing this long 20 mile round trip day hike. Throw in 4000 feet of gain and you can bet my tank was empty when I got back to the trailhead. Big cloud buildup but at best at bit of a spritz from time to time. Lots of snow, bugs and wildflowers.
