I carry a 2 1/2 ft ( might be 3 ft) screw anchor that I found at Tractor Supply Co. It has a helical plate near the bottom and has an eye on the top. I used longer anchors at the phone co, when I worked there for temporary guying loads. It depends on the terrain you are in. This works better in sand of course It can be screwed in or, dig and bury. They worked well at work. I don't know how much strain they will take. I may be the anchor that gets me out some day.
