Follow up to a thread from yesterday...we have a portable course that stays up all summer but we need to move (remove entirely and reinstall in different location) about 5 times a summer. One person moves it using a fishing boat. I would like some thoughts on what is best to use for end course anchors. Leaning towards 30lb river anchors, but open to other ideas. Key is that they hold well but one person can get them up and into a fishing boat wihout killing himself. Thanks in advance for any ideas.
