Absent the $1000 in spending money that Jarhead suggests I think a motorized electric bike and a portable solar charge could come in handy. I’ve seen some of these bikes sell for $300 brand new online. Throw in a good $100 fold up charger and you can augment your leg power for distance and steep uphill climbs. It’s not a best case scenario and it would still take a good month or more to get home from 1000 miles away but it will definitely speed things up and may save you a heart attack. You would just need to make sure the electric parts were hardened from an EMP.
