a few of these have been mentioned before....
the smell of rain
the smell of a roast in the oven (turkey, chicken, beef, ham, etc.)
making our little girl smile/laugh
playing bass
hearing peter maher yell, 'YEEEAAAAA BABY!!!!' ...gives me chills every time!! i love it!
knowing a guy has you totally beat and somehow still making the save
related to the above... seeing the puck go by and hearing it clang off the post/crossbar.... or is it more of a 'doink!'

fixing stuff on my truck and the satisfaction of knowing i was able to do it myself
the smell of apple crisp in the oven (crap... now i'm salivating!)
getting out of the city and just enjoying the quietness
