Another recipe sent to us from the biker dudes on the other side of the mountains, this one packs the kind of heat your lips will remember....

1 jigger each:
grapefruit juice
lime juice

Feel free to rim your glass with salt--or not
Add above ingredients to your glass and stir
Fill with ice
Top with club soda
Add 1 or more drops Habanero Bitters (really-a drop at a time!) and stir again
