Garnet earrings; Montana Agate and Garnet Bracelet. A few years back I drove out to Idaho for a show and got pulled over for speeding in Montana. Now, it’s not as exciting as it sounds, I was only going 48 mph on the highway. In a 35 mph work zone. I had taken my foot off the gas, but hadn’t applied the brake. The cop sitting there noticed. Anyway, after talking to him, I pulled off at the next exit to get gas and stopped in this little rock shop where I found these cool agates.
