My local hardware store puts the cattle panels on sale for $19 once or twice a year and I always buy a few. I must have 30 of them stored in the equipment shed. Another 10 are in the garden. Except the one in the garden that my husband backed over with his truck, I've never had to replace a panel. They are VERY sturdy. Like the article indicated, I cut them with a large bolt cutter thingee.
Thank you lysie. I’ll show it to hubby, maybe we can use somethink like that for a temporary greenhouse in the community garden. Even use trellis panels in the garden.
