Shuttle hike starting at Cholla TH. Watched some squirrels (VERY exciting...) until my sister made it to the top. Also watched some guy throw what was left of his smoldering cigarette on the ground. It was about an hour before I started to head down. Finally found the "cave" I've read about, too.
Last time I was here my time was 2 hours and 10 minutes roundtrip. I think I've improved quite a bit.
