Check with the brewpubs and see if they know of any other homebrewers in the area and see if the good one would be willing to host a meeting. They will probably even let you put up some flyers. Something along the lines of - "Do you brew your own beer? Do you want to learn? Come to a meeting of the Fruita Lager and Ale Brewers . . . "
Ok, I get it. I'm not saying everyone will give up homebrewing obviously, we've got lots around here. But maybe not as many as if we had bad beer.
Maybe I live in an anomaly; we currently have 141k people in our county.
1 - Good brewpub (occasional cask ale)
2- Terrible brewpubs (one may come back around)
1- future brewpub (unkown brewers) which may open around spring
0- good beer bars
0- homebrew clubs (seriously not one) (may change if i can find a couple more interested brewers)
You might only get one or two people at first, but it will grow eventually.
PS - I just named your club FLAB
