To be honest we really do not have a trail plan yet, I am flexible as I have done them all plenty of times. I have not even looked at the trail melt situation yet. 4th of July is really way to early for Silverton( or Colorado trails in general) but the parade, fireworks, and heat in Albuquerque make it a great time. We usually take the kids to the Hot Springs in Ouray one day for a couple of hours, and some times we will do something like hit the mine or Mill tour. All trails except Poughkipsee our SUPER easy. Black Bear is generally not open on the 4th anyhow, but even its relatively easy with decent gearing. Where we camp is just a few minutes off Red Mountain Pass, before it gets steep.
