Lucky for me I have a nice creek behind my work I can walk to that has plentiful gold. Got this with my pan, shovel and 1/8" classifier in 30 minutes on my lunch break. Same creek that I usually sluice after work. Aint much, but it feeds my gold hunger while Im at work!
Also a good way to diet. Spending lunch time panning instead of eating you're burning calories instead of adding more. I used to do the same thing only with a small hand-launch R/C/ glider I kept in my car. Go out, toss it in the air and ride the thermals that came off the blacktop of the parking lot.
