Welcome Seattle Sounders! We've got some great local clubs around that area, and like Dibo said it really depends on where you move to
A lot of the MAA teams will have a few older guys in there! I know Kariong have some great social MAA teams, as do Gosford and East Gosford.
Im gonna be trying to live close by a train station (Gosford or Woy Woy) as ill be working downtown. My Brother in-law has been associated with Southern Ettalong for years but he said he wouldn't recommend it for a a new player haha not sure why. Here you just put a team together and pick witch city league you wanna join based on the teams ability, pay the fees and play all year round summer,fall,winter,spring. with 2 weeks off between each season.
Sounds like its a lot more organised over there. Looking forward to playing in warm weather!!!
