This is the second cache that we placed on this trail. This next bridge is the biggest bridge you will cross!
The Mike Miller trail is a fairly easy mile loop trail. There are a bunch of easy flat sections, but also a few spots of moderate uphill or downhill hiking. Overall though, it's a beautiful trail that can be done start to finish in less than an hour.
The cache itself is a tiny Altoids tin (with some modifications). You DO NOT HAVE TO LEAVE THE BRIDGE to grab this cache - it is 'grabbable' from the bridge itself. I hear that it's especially attracted to metal surfaces.
