Hey Tom,
I live in Appleton, transplanted from the South about 8 years ago (i.e., I'm the one wearing long sleeves in the summer!) My daughter and son in law live in the Muskego area.
Yeah my hobbies tend to turn into obsessions, and usually vice versa too!
I brewed about (shudder) 15 years ago or so and really got into it, but moving around and getting kids through college took away much of my play time. Last year the son in law got me a simple extract kit for Christmas, and while it turned out awful (not the kit's fault, our stove could barely keep the wort simmering) it got me hooked again. Now I have a propane burner so a full 8 gallon boil should be no problem.
