Twice monthly I go to the middle of nowhere. I cannot take my amps.(guitar and bass). So I practice unplugged. That's no big deal. The problem is that each week, for a summer camp thing, I have 2-3 songs to learn. When I go, it is a whole week surrounding that one day. I have no Internet, so I can't look up tabs, or even listen to the songs. I cannot negotiate when I go. How do I practice around this?
