Mountain Biking!
I have to admit I don't have an excellent $3000 bike, so I won't put a picture of it here. It is, however, a very tough Diamond Back Apex with many scratches and dried blood patches on its large and imposing 23 inch frame.
I bike strictly in Marin, including trails like Pine Mountain Loop, Bolinas Ridge, and Mount Tamalpais. Here's a photo of a trail on Pine Mountain:
I bike with some pretty tough bastards, and we all recently went out on a long 5 hour ride. It was our going away bike ride for Scott Gray, who was an excellent comrade. We will all miss him. He was dragged into moving to New Jersey (Arggh!) by his evil and conniving wife.
