It looks like the event schedule is April (7), 8, 9, 10 -- the actual Machine Gun Shoot begins the morning of the 8th, so (assuming that the traditional opportunities hold) the crew will arrive at the Golden Manor on the 7th, and the early-bird/nightstalker sale (with cheesecake) will be that evening. If you are traveling long distances for the best selection available at that pre-event sale, remember to account for time zone changes to avoid late arrival disappointment. If you're going to skip the pre-sale and try for Friday morning, be aware that opening-day crowds entering the range back up onto the highway -- allow for at least an hour's delay, quite possibly more.
