Football

tl;dr We said local team.

Wife (Chelsea) - no chance
Me (Cambridge Utd) - couldn't do that to her - rarely get to go to games anyway (maybe one a season if that) - So fan, much plastic

Local teams (in order from closest to further away): Fulham (we can see the floodlights from our flat and, on a good day, hear the crowd), Chelsea, QPR, AFC Wimbledon.

AFC will be a bit closer (probably 2nd closest) when/if they move into their new ground back near Plough Lane, but decision already made by then.

We let her[1] choose and she chose Fulham (ok, with a little nudging) as we're more likely to go see them (tickets are easy to get, cheaper than Prem and the standard isn't that bad) and they're the most child friendly[2]. Several family friends are season ticket holders too.

Chelsea coaches come into her school a few times a week for before school club and some PE lessons (I believe Chelsea and Fulham divvy up the local schools between them to avoid treading on each others toes).

1. She's a bit of a tomboy; loves football, cricket and rugby. Can happily watch any sport on telly (I caught her watching snooker the other day after flicking past all of the usual cartoon channels). But still likes her ballet, playing with dolls, dressing up, etc.
   
2. She'll still hear a bit of bad language (no point pretending you can shield her from all of it, she'll probably hear loads from the older kids at school), but not someone shouting "CUNT CUNT CUNT" throughout the entire game.
