Hi All. Iam About To Make A Hoop Run Also. I Dont Think Ive Read About Anyone Using Thiner Re Bar ,maybe 3/8s For The Hoops. They Bend Pretty Easy. I Made A Bird Feeder Station, From 2,i Belive They Are 15 To 20 Feet Long. I Just Stuck One End In The Ground And Walked To The Other Side. They Bent Easy I Was About To Buy Pvc. But After Reading About The Weather Cracking Them. [ I Live In The Panhandle Of N. Idaho. Gets Real Cold ] I Think Steele Is Better.i Tied The Cross Top With Wire. Its Been Up For 4 Years . Just A Thought!
