It is no longer tied up in court. If you are legal to own it, you can OC it. However, you may have noticed a flurry of new "no firearms allowed" signs at your local stores; it has been rumored that some law enforcement agencies have even distributed "sample" signs.
Please use some discretion when doing so to avoid any negative publicity. Remember that some ninny's are frightened by the presence of a firearm.
There are some links in there.
I find that the only time I really utilize OC is when I fuel my car. I buy ethanol-free, which seems to only be sold in ghettoish areas of town. Instead of my pistol sitting on my seat in the car, it is in the holster clipped to my pants pocket (I pay at the pump).
