While I get the not-bothering your friends and family thing, if I was going out where I was knowingly going to be away from civilization, I would have a conversation with a few folks beforehand. Yes, it is a favor to come get you. But you can pay for gas, wear-and-tear and time if they will let you. And, you can be there for them in an emergency. I assume you are not planning on making this a habit, so a one-off situation isn't that big a deal. Talk to your friends/family before you go and let them know your ability to do something you love depends on having a fall back plan. I bet you will find they willingly step up (once, at least).
