That's easy. If this person lives more than 15 minutes away in traffic, it requires effort. Dating is supposed to be effortless, right? Quantity has nothing to do with it if men nearby won't leave the internet alone.
Seattle, gay friendly town full of unfriendly gays. Un-hookupable if he has to pay bridge tolls, $12 parking, or sit motionless on I-5 longer than 3 minutes to meet you. I felt like an outsider as my tech job was always 20 miles away from Capital Hill (where there was always a craigslist meeting within walking distance.)
Los Angeles. In their defense, it can take two to three hours to drive from Los Angeles to Palm Springs. Guess where my job is? Halfway between them.
I don't think I can give "Enron by the Sea" a fair shake after they forced their mayor to resign just last week, so I'm going to leave that one alone. Los Angeles gays are a whole lot easier to talk to than San Diego. Only variable is I worked for a major employer there and didn't want to stumble on a coworker while making out with someone else.
