I have an option of storing my tack at the barn in the tack rooms which now have a lock and key.
They never used to be locked (for about 15 years!) until last Christmas when someone came in and stole a bunch of the BO's tack. After that, the lock went up.
I used to store my tack at whatever barn I was staying in until I started at a facility of 150 horses that was half a mile long. Instead of putting my tack in one place and having to walk back and forth all day to tack up horses at different locations, I would keep it in my car and just drive there (nothin' lazy about ME!). Not only did this help out time-wise, it also kept it from any stick hands that were around...and there were a LOT.
So I got into the habit of taking my tack with me instead of storing it. Its always in my car, ready to go. Its always at home when I need to oil it. Its always at the barn when I want to ride, simply because its always with me. I never have to worry about where the tackroom key is, and if my tack with be there since the tackroom is shared (I had a situation of polos missing for 3 years before I finally found them. They were accidently left in the tackroom after I left the barn and someone had taken them. Just finally got them back by freak accident)
Do you store your tack at the barn? Or does yours travel around like mine? Is your tackroom locked? What keeps it from missing? Do you put your name on your tack anywhere if you do leave it?
