Why have few paleo artifacts been found in any one place?

Few artifacts are found in one place at a time because the native american people moved around a lot. 

That president would be none other than president warren g harding , return to say of life before wwi

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
