I cannot bend over and exert myself physically due to lung disease and wounds from the military. I am legally disabled with paperwork and sweet parking placard to show for it. I am trying to find information on the americans with disabilities act protections for prospecting. In particular i need to be able to prospect standing up such as using a high banker or the gold cube and trommel but pretty much every state prohibits using mechanical classifiers thus i am unable to prospect on public lands as a healthy person can. Any lawyers with advise?
