Hi, Covid boredom has caused me to do a lot of things including updating a 10 year old piece on Rockhounding Tips including a new section on Truck Camping. I offer it to you and any of your friends, clubs, etc. Please feel free to use it. John Scully https://www.iminethem.com/Scully's%20Minerals%205.16.19/rockhounding_tips.html
