They started with 7 and are down to 3 (1 of which is standby). They're old. Made in Tampa and barged up here before opening. Somewhere here I posted an old newspaper article with a picture of them craning one into the water. I recall they were a day or two late because the barge ran aground on the James.Im not saying they would take them out as long as they are not a large cost but I feel if it ever came to the point where they needed a fairly expensive upgrade or repair they may not see the need anymore.
