The items you find may not be that exciting to you but they definitely show that you are on a good spot with a lot of age. Something good will turn up.
A bad day detecting is better than a good day at work. At least you got out there and had some fun. Oh...and your bad day looks way better than my bad days!
Nice point there in the center, and the pottery chips, harmonica reed and a few other relics tell me you may still have some more good finds waiting on you. Keep the faith, and good hunting!
