My club has a 21 day rule. But flying elsewhere counts, provided that you get a signature (the club just wants to know that you've flown recently, it's not interested in making money off you for check rides).
But this can be a bit dodgy ... on one occasion my signature-from-elsewhere was for floatplane training, and I hadn't actually flown a landplane for a while, and the crosswind landing was a bit not-very-good. (Hint: there aren't any crosswind landings in floatplanes on sufficiently large lakes, you just land straight into wind.)
