That photo is courtesy Jim Flynn, taken before he and wife M.J. Benavente opened the doors to Snap Fitness in Jefferson Square (next to Subway, on the 42nd SW street side) just moments ago. We told you about their enterprise back in August (Jim’s a longtime WSB’er). From hereon out, he says, they’re open 24/7 to members; you can drop by for a tour 11 am-1 pm or 4-7 pm Monday-Thursday, 11 am-2 pm Friday, 10 am-3 pm Saturdays, or call 206/299-1597 if you want to arrange a tour for some other time. This is a “soft opening”; they’re planning an official “grand opening” celebration next month.
