We have purchased this Groupon to the Copperhead Gem minining for the past several years. The first couple of times were good and my kids enjoyed it, however, the last time we went the lady running the place was very unfriendly. Also, the first Groupons we purchased allowed for a large bucket of "gems" to mine. The last Groupon was about the same price, but we only received a small bag of gems to mine. We weren't anticipating receiving such a small bag and my kids were disappointed. That on top of the lady being rude made the experience negative and I doubt we return.
