I'm in a similar situation to yours. My next of kin is 6 hours away and I have a friend here that I either text or call before I take off and then when I get back to the parking lot. Yesterday, I went on a ride that I would consider sketchy at best as it's densely wooded and limited cellphone reception. I am in the market for a SPOT but I haven't seen any yet, not sure where to pick one up? Either case, the phoen works well, as does the flight plan that someone talked about. I always leave one on the front seat of my jeep, flipped over or folded up so no one knows where I went just by looking in my car. I also carry a gps that is meant for the 'rode' (garmin nuvi) and you wouldn't believe how helpful it is here in the East to know which way is toward the parking lot. Helped me from getting very lost last night. Always pack something to eat and a light in case you get really lost and will be riding in the dark. Just a cheapy $25 light for your handlebars is good enough if you aren't intending to be out riding at night. Remember, the days are getting shorter so plan accordingly.

I don't have a road ID but in my camelbak I have my old driver's license that expired with a sticky note with all my emergency numbers. I also have my new address with the phrase "I have a dog" on it, in case something happens.

I really need to get a spot. The best thing about that is family far away can keep an eye on you, not just when you are riding but in general.
