The Dome

Track, turf, free weights, weight machines, batting cages — The Dome covers a wide range of interests. Until I bought my Icebugs, I was terribly averse to running outside in the winter. Enter: The Dome.
The Dome is NOT flashy. You get a cheap membership (mine was a family membership @ $ 599 annually, split between 5 people, so essentially $ 10/​mo. Individual plans are $ 60/​mo). They offer free fitness classes (one per night, week nights only) that are rarely well-​attended. I’ve seen classes held with only one person before! Talk about cheap personal training/​instruction.
I joined because my running group meets there every week. The track at the Dome is the largest indoor track in town @ 413.5m, so you get just under 4 laps in a mile — slightly less boring than a smaller track.
The Dome also has some kind of Kids Night thing once every quarter or so, where parents can bring their kids for the evening and the kids will be reasonably entertained in an active way. While I’m not a parent, some people might find that a bonus.
Least boring place in town to run in a circle for an hour or more, and it won’t hurt your wallet.
