I remember my first beer! Just kidding! Need to hang same tacky ornaments on the arms. So tacky you can’t avoid seeing them every time you walk around them. :B
We also hung something on it to catch your attention. We do the same for tent guidelines to prevent tripping. Our current awning arms are up so high there is no chance of hitting it unless you are 10 foot tall.
I am happy to be able to say I've never walked into the awning supports. They are definitely in the way though. Using the awning in car port model (like wildtoad mentioned) does make them more visible.
