IMO, it will be a nice addition especially on a drive by at night. This location probably is one of the highest traffic counts in the city. Will I go take a close look of it, probably not, since I rarely go to the fairgrounds.
It more than likely will have some awesome LED displays.
Another thing, the horse shows and the money brought in from them are probably one of the biggest incomes from out of state visitors OKC has. Hell, Captain Kirk spends a couple weeks here every year.
