Bird watching - Feed them fresh fruit - Baltimore Orioles love oranges and Cardinals love grapes. Orioles love grape jelly too and if you put out either one, woodpeckers really like them too. Butterflies like them too.
Holly this what u do with all daves messed up bike rims and put in your garden. I love this idea! I could mount old bicycle wheels/tires/rims on the side of my old shed and let the vegetation climb! Fabulous up-cycle idea!
