I'd like to hike up Half dome before they close it for winter this year. I'm in pretty good shape for hiking, recently did a few 10-15 mile hikes in yosemite. Let me know if any one of you are interested in joining me to do the following trails in the upcoming weeks or months: 1. Four mile trail. 2. Yosemite falls trail 3. Snow Creek trail Finally half dome depending on the permit lottery
