As someone who is recently single, and flopping horribly in online dating. My main hobbies are motorcycles, electronics, computer gaming, and starting into target shooting. Chances of organically meeting a single female during one of my typical free time expenditures is almost 0.
I find sports in general to be drole and a waste of time. I don't drink at bars and find the idea of just randomly meeting a perfect match at a random bar so astronomically unlikely I want to punch people that suggest it. Also going out to drink... Then driving home... yeah no.
So if your not around single females, and can't see yourself going out and just trolling a bar for maybe that one in a million... what do you do?
