Ive done the Merry go round and still didnt get into deco if its the 1st dive of the day so youll be fine. Table rock is at 270ft and with the flow after tying in , you may not get much further than that . Im glad I dont get tired of caves because they have a few scratches on the rocks, big deal. Youll be doing good to see the big line arrow at the tee on 6ths.
