I have dived Richmond beach many times. There is some debris on the bottom, otherwise not too much to see. There is a pedestrian bridge over the railroad tracks [i.e., carry your tanks several hundred feet up and over the bridge. We found some big concrete anchors and an old steel propeller {14' across?] at 60 feet deep that were used as temporary anchors. Look carefully and you will find they are attached to each other by big steel chains. These were straight out from the bathhouse. The biggest hazard is trains, at least one child has been killed on the tracks.
