Looking for solid tent stakes that can be driven through hard ground without bending easily. For my Seek Outside tipi, I've had bad experiences in high winds and I like knowing the tent's not going anywhere. I've been using 10" stansport stakes that cost only 99 cents, but they do bend and the plastic tab on top breaks when I use a shovel to leverage them out of the ground. This is for car camping only so I don't care how much they cost. What are you using?
