if you are able to be on the beach where chuck's stood at the perfect time it is very, very, very possible to walk away with hundreds of 1/2's. the beach is narrow at this spot and when black sand and rocks are exposed it is possible to find them every 4 to 5 steps.
conditions have to be perfect, and if you are not their at low tide right after the storm, the next tide will dump sand back on the beach.
it could also be a dangerous place because of the surge. make sure to have a waterproof detector and a set of eye's on the back of your head.
it will take a real good hurricane to move all the sand that is on this beach now. the wind and waves will have to hit the beach in the right direction for this to happen - thanks to tax payers dollars going to waste.
i lived in sunnyland beach back in the late seventies and have seen many items come from bonsteel park and to the north. some are encrusted and others are not. lots of stuff in the dunes.
oh one other thing-if you dont live in the area or have someone with you that lives beachside expect to go to jail today. times were different back then. my friend still lives up their on the beach and his son has been questioned by the police several times after a hurricane.
if you don't have proper i.d. you will be arrested. even though the police will be metal detecting on the beach and tell you that you are not allowed - they will still do it. my friends son has video of them in 2004. eight police metal detecting and they would walk up to everyone on the beach and ask for id. just be careful and be smart.
