I was in your boat a few years back when I first started. I'm only 20 (I say that because it's usually easier for young kids to find more people because it seems every other teen-young adult down here smokes heavily) and about 3 years ago I went to VooDoo Music fest down in New Orleans with an old friend and his newer group that I wasn't that familiar with. I just casually brought it up in a conversation with the new people I didn't even know and out of all of them it was my oldest friend who was happiest I had some. There were no signs, he never mentioned it and I would have never known if I didn't speak up (because I wanted to and didn't want to wait around all day not smoking the joints in my pocket, but I didn't want it to be awkward). Anyway, I guess somewhere in this message my point is you never know. Just be open and polite about it, don't come off as a stereotypical stoner, that always attracted the wrong crowd for me. I like the more mature smokers who have fun will doing it but shut up about it after and in public. What also worked for me was bringing up pot in a normal conversation but have it be related to recent news. For instance : Medical Marijuana Becoming Legal. You can instantly pick out the uninterested and the ones who enjoy it. Trust me and give it a shot, but at the end of the day even if you're alone, at least you're stoned right?
