Your Best Moment of Audio Exuberance

My girlfriend stayed home today while I drove her car (circa '98 BMW 740i with CD changing factory stereo) to a New Year's day party. While I find her 740i to be an underpowered, overweight, undersprung yuppie saloon with a screechy, bloated stereo to match, I must admit it was, nonetheless, great fun to crusie along at 80 MPH and ABSOLUTELY CRANK the Los Lobos CD that her brother gave me for Christmas. (The band was new to me -- has anyone heard "Oh Yeah" from This Time?) It almost reminded me of the good old days that got me into this insane hobby -- just being young, listening to music at high volumes and having a good old time. What setting, atmosphere, equipment or musical selection gives or reminds you of your happiest audio moments?
