i agree it is possible if you spend most of your time in nature. i did 6 weeks solo off 1.5k driving up and down the east coast this past summer. i did some cities and enjoyed free museums (washington dc), skateboarding, and catching concerts. if there are any big events (music festivals, conferences, etc.) that you want to attend, then hit them up a month or two in advance to see if you can volunteer in exchange for attendance. everyone could use help collecting trash lol.
