I usuay do what Eric did, usually pick up two or three anchors a year toggin out on the reef. Seems we have alot of rich fishermen in my area that prefer to cut their lines instead of pulling them out.
We have cought them on rod and reel and pulled them up on our anchor.
Alloy - I've got a few gnarrly ones you can have if you want to pick it up. If you hang it who cares.
