Doesn't it violate the code for proper usage of the flag to use it in any way other than its original intended purpose?
Looks like a grey area to me. Flying a flag in your yard is allowed and even protected by the flag code, while printing it on drapes or clothing is forbidden and considered disrespectful. Assuming there's no business logos being stuck on top of it and it's for personal use with patriotic intent, is putting it on your Jeep closer to the former or the latter?
