Also there are GPAA gold shows that travel around the US, there was just one in Fresno last weekend and they won't be back here in California again until next year. It was fun as they had raffles for gold nuggets, metal detectors and you could pan for free gold too, if you ever plan on going there bring lots of money, I really regret not bringing enough to buy more stuff there.
