Lookin' good there Pat. Looks like great weather. I miss being there with you guys. Hope you find a bunch. I know you'll have a great time!

Awesome Pat, been following you. Thanks for the Tromel you sold me. Can't wait for my trip next year on the feather.

I hope you find some GOOD gold to. Such a bummer to find bad gold.

Good to see you Pat. May your pan give you a gold smile.

This shows another Mini Max in operation. New customers first time out with it. Up on pat's Yuba bash outing Everyone is telling up that they are having so much fun, Plus this has been a good year for finding gold due to all the heavy rains we had this last winter. Mining is such an adventure that not everyone understands. Unless you go out and actually experience it you just do not know. Plus being up in these mountain towns is an adventure on it own. There are a lot of other adventures that are associated with Mining, as well as Hiking, biking, camping, fishing , swimming, and more. ... See MoreSee Less
