I am sure you know by the name where to look for this one. It is a 35 mm film canister with a log only. Please bring your own writing stick.
You may have noticed that I started this little series with a 3 digit number. Before I am finished with this series predominantly on the North side of Jacksonville area, I expect to have more than 100 of these. That is, I will if I can find over 100 of these sites over 1/10 of a mile apart. Enjoy!!!
