For the away game: if it's early kick off (always seems to be) get up, have a shower, go for a run, eat some breakfast, listen to some metal to get me in the mood, maybe read a few things on here, then onto the tube at Tottenham Hale which will be full of goons, meet my dad or whoever I'm going with (normally my dad) at Finsbury Park. Don't normally bother with the pub before the game at their place these days (especially if it's early). Go in relatively early, meet up with a few people, have a singsong in the concourse, watch the game...then what happens after depends on the result, but hopefully celebrate in the most decadent way possible.
For the home game: go to various pubs in Tottenham before and after regardless of result.
