Stealing a board is just f***ed up. Its pretty rare here in Japan at least where I board but this year I will be locking it up. Taking them from outside the medical facility is doubly f***ed up. I can see why you wouldn't lock them up there.
Hope you find them and make them pay.
Stealing someone elses board as a replacement is one of the stupidest things I ever heard. Then we will all become thieves and paranoid about our boards.
Maybe in 15 years we will have racks with built in locks that take your fingerprint when you put it in and thats the only way to unlock it.
could be done now but the problem is the cost.
