I'm thinking about developing some kind of hobby. It needs to be something fairly cheap. Or at least something without many recurring costs. Preferably something that will require me to leave this apartment. I was thinking D&D would be pretty fun and it isn't too great a deviation from things I'm comfortable with, but I could use an activity that would expand my social circle. Martial arts is too expensive. The Klingon language would involve me staying here, similar problems as D&D. Collections generally cost a lot of money or involve traveling distances outside what I'm capable of. I need suggestions.
