Yeah don't get bitch slapped by a real one in public for wearing a hat or anything, but maybe the girl with the iPhone mud-protector's just sick of young guys who won't get their sneakers wet. She might saw cowboy, then see a manly MMA fighter, construction worker, or even CEO, etc. and say 'close enough'. It could just be masculinity she's itching for.
Also, two girls I've been seeing in casual relationships both still think they've got a shot meeting someone for a real relationship off of Tinder. I also have the best stories by far (like early a.m. straight to doorstep/bedroom) from girls whose bios on online dating have said things like no players, etc. As always, there's big discrepancies between what people say they want, then actually let happen to them.
Finding some sort of connection can be pretty useful to get matches though, so displaying a general love for the outdoors could help, though maybe the novelty of being someone in from NYC etc. could too, you know?
p.s. these young girls may all be walking around within a few blocks' radius on campus...
