Depending on your flash flooding if,concrete cinder blocks float down stream

On those set with no other options. Got several railroad plates from railroad employee 45 years ago. Probably illegal in these days and I would leave them year to year and make set I wanted. Did not have many as I could usually do something different. Dogsniffer to move. When pogos came out I was sold. Of course the plates had there use and would guess someone else are using them or they are still in spots not used.
