1+ on the military surplus stakes for smaller structures. They are aluminum and super light, also about $1 each so you can't beat the price. I usually carry a bunch extra and hand them out to people setting up their tents in the wind.
For my big 16' shade structure held up with oars I quit screwing around with stakes which always pull out, or deadmans that take a lot of work, and instead I do this:
Yes, I bring a drill with me. Why?
- These are cheap for their holding power, ~$6 each. I did have to slightly modify them to get them to dig better (cut off a bit of the lower digging tip so it didn't circle entirely on itself, and hammer it down to make it a steeper angle).
- I can setup a huge bombproof shade structure with a few people in 10-15 minutes that I just don't have to worry about. Recently some stitching on my shade structure ripped before the anchors failed.
- You can setup the shade structure in and around plants without disturbing the soil which you can't do with a deadman.
- This works in cobble where you wouldn't want to dig a deadman.
- Literally longest part of installation/uninstallation is threading/unthreading the loop from the top on each anchor.
I have thought about making a bunch of long stakes with aluminum angle as mentioned earlier, especially for more heavy rocky soil where these anchors wouldn't work. But driving them in can be difficult and pulling them out can by
really difficult.
