Indeed... that is a crap load of money right there! Cash pay out of $225M plus!!
I'm not sure what the first 5 would be, but the first would be to get w/a lawyer and financial adviser to take the best first steps. Next, I'd have to look at the family (kids, brother/parents/etc.) and make sure they're taken care of. Then I'd guess I'd have to really sit down and think what do I want to do when I grow up (hahaha). I'm sure my racing budget would have grown 10-fold .
What I find humerous is that there are quite a number of folks that won't buy a ticket when the lottery is a measly little $180M, but when it becomes worthwhile... say over $375M, then they're in. I'd be one of those folks - LOL
Build my compound in either Idaho or Montana that is only accessible by 4 wheel drive or snowmobile, screen every phone call and prepare for the zombie apocalypse, cause I know with my luck, the world will be ending soon...
Plus have a stable of track day bikes at different locations around the world.
