Whoa, July 20!!
Due to the significance of the date for you, and the hikers attending this, I'm tempted to meet you guys and do what we did last time. I've got a kid I want to take up to Cathedral this summer, and if people I know are going up, that could be a great day! It's only a couple of days before my family leaves on a big vacation, though, so not sure.
And you retired guys hiking mid-week... what's up with that??
...and hope for a non-windy day, too!
