My friend Adam and I have done a couple of local hikes now and today after work we went and did Mailbox Peak off of I-90, just a little bit past Mt. Si. The hike was shorter in total mileage than Mt. Si at 2.5 miles, but had more elevation gain at 4,000+ feet. It was a very pretty view of the Snoqualmie area from the top.
