Jesus...I just read 10 pages on this topic and in that time, I took my iron covers off twice...and replaced them twice...then decided that;
1. covers will stay on during travel in the trunk
2. Immediately upon leaving said trunk..they shall be removed. (If I see any golfers that look...you know..like they're good, I will pretend to do something else until they leave so they don't see my headcovers)
3. I will play golf
4. After golf...clubs will be cleaned and returned to vehicle...after re-covering said irons.
5. I will pray that the sound of clanking irons doesn't drive me insane by hole #2.
It is so damn funny there are 10 pages of this topic from 7 years ago....and even more funny that I just read them all...I was sober to start..I'm half lit by now. Bedtime.
