Yep, it certainly is annoying. My last one (from VA Beach) was about as thin as tissue paper and cut just big enough that you couldn't fit it in a standard wallet pocket -- very annoying.
Most recent one (Fairfax County) is actually the right size, but still a flimsy little thing. You'd think they could make it like a drivers license or something. But hey, I guess they have to have some way of poking us in the eye, right?
