Who here leaves them in? I always take mine out. Bashed a shin on a buddies the other day. He always leaves his in. I don't understand why, unless it is just to fugg people up.
I take mine out for three reasons.
1. It hurts when I bark my shin on it.
2. Just about every thieving bastard out there will lift a towbar as quick as look at you.
3. In NSW it is a legal requirement to remove the towbar if it is removable.
