When I've needed to, or when I happen to be in that situation, I have had a lot of success with picking up guys in bars, it can be surprisingly easy when you learn to recognise the signs of someone who might be interested. But as a long term strategy I wouldn't like to depend on it. If you return to the same place repeatedly you quickly get sussed. If you're in an area where there might be stings then it's a road to nowhere. I've always found that establishing a circle of regulars is the key. Be very careful with contacts from backpage, craigslist etc. There are good guys but few and far between IME.
