The 5th largest city would have about 1.5 million people in it, plus the population of the surrounding areas. I find it very hard to believe there's not even one alternative program meeting available in the 5th largest American city after some 20 years of SOS, Lifering, Smart, and others have been operating. Seems impossible that would be true after so long.
If it's so that there is nothing and you don't mind waiting for slow keyboarding, there are some online meetings, and combined with that even if you have to spend a day driving perhaps making one f2f meeting every other month or so may help a little.
