go see live music, play music, bust out the djembe or guitar whatever you play, read something, write something, draw something, watch a good movie, smoke another one, listen to some sick music, make love, go for a ride, go for a walk, so many things to do. What you do normally when you're chilling should only get better when baked.
create something! with paint! and happiness! run around with a camera and take obscene pictures. watch 3D movies. drive around listening to sweet music. and please, please, try riding a bike. it's hysterical.
