I kind of gave up on NA. About a year and a half ago, I tried going to a few meetings and ended up going to empty buildings (one with a No Trespassing sign!) and asking maintenance workers at a church where the meeting was. I figured that I should just go to the places I was familiar with rather than looking for meetings that may or may not exist.
I just checked and the three meetings are still on the list on NA's website. Maybe it was just one week that no one showed up to these meetings or the list is out of date.
