I'd also recommend joining the Rails to Trails organization. You donate some $$$ to a great cause and you get on their mailing list for their quarterly magazine. It highlights different trails, both long and short, from all over the country. Only downside is that it seems they are constantly asking for renewals. I re-up every year, but I swear they ask for renewal every other month. Becoming a member also gives you access to their website that lists a bunch of local trails you may not know about. So, not really a magazine subscription....but still cool to be a part of.
