Need advise. It has been a few years since my last trip to Las Vegas. Does any one have a feel for how long they will have this strike available to win? I will be in Vegas Wed. Mar 9. I wonder if I will be too late. I remember when they were 12oz. and generally $200-$300 play would be needed to win them. Now I know they have much less silver in them.. Does anyone have a feel for now much play it takes now of days to win a $300 strike.
