2mil, even after taxes that will get a person on the Charlie Sheen path, Hookers and Blow.
When you think of it if you had roughly 1.25-1.5mil after taxes most people could have that burned up within a year I bet. Hopefully the winner is someone that could use it.
30yrs ago, if you won that much you could've walked away from work forever. Today, like I said, it'll take the bite outta things you need to worry about. That's assuming you can let it start to work for you and resist the temptation to churn through it all. Done properly, one could probably lop 10+yrs off the end of their career.
Or, as you said, you could buy a nice house, a bunch of brand new depreciating assets like cars, boats, RV's, ATV's, etc. and have it all spent in 12-18Mo and wonder how you're going to afford the taxes on the house, the Ins on everything, and the maint/licensing on all the toys.
