We live in the Northern section of the Tahoe National Forest in the Lakes Basin, just below the world famous Sierra Buttes el. 8000', ou may have seen the Buttes in the Vin Diesel movie XXX.  There is world class mountain biking here.  If you train on this terrain everything else seems easy.  The elevation matched with the rocky singletrack makes for ultimate fitness.  We also do jewelry.  I used to be in the jewelry business doing semi-precious repairs.  Now I am in nursing school, so I am selling off my collection.   Please email me if you have any questions about my feedback.  My biggest score on ebay was finding Ted Cutgems.  He sells the best CZ's on ebay, which rival moissanite and asha as only $15/carat as opposed to $550/carat!  I compared asha next to his and there was no difference.
