I recently moved from Atlanta and was pretty active in the tennis community (was captain of my USTA and ALTA teams) I am a little rusty at the moment but am really interested in playing league tennis here as well.
I know for winter most of the play happens indoors - and more of those facilities are private so not easy to meet people who need players for winter season.
Anyway if anyone knows the secret code please let me know (lol) I am able to play either on a 3.5 or 4.0 team.
I suggest you post this in the local Denver Group in your area. Click the Group tab at the top. There are discussion boards in each of the local groups - that might work better than in here which is the international general discussion forum.
