well winning 300 mil would have a pay out of about half which come to 150 or then figure 30% for tax's you need up with 100 mil.

First i would spend alot of time finding at least a 1000 up to 3000 acres. maybe a old hunting ranch or some govt. land

Then i would build my compound a nice house with a fence with razor wire around it.
A bomb shelter because come on guys we know Russia and china want are A * * not to even think of the terrorist.

Then i would build a garage big enough to hold 10 car trucks boat or what ever i wanted. a building that would be for a pro shop\gun shop. because come on guys if i bought all the guns i wanted the FBI would knock on my door and shoot me dead. so thats what the gun store would be for.
I would build a indoor shooting range for both gun and bow.

I would pay some pro off of the outdoor channel to come tell me how to grow 200 class bucks. properly the management advantage crew.
I would build a 50 to 100 acres lake.
Build enough food plots to feed the deer in the entire state.
then if i had anything left i would build a few cabins for all my Buddy's on here to come tell me how nice my land is and ask if they could hunt it. Of coarse i would let you all hunt it.
Ohh then i would take a year off of everything no traveling no spending money just hunting eating and sleeping to get ride of the headace i would have after doing it all .
I could drop a 50 mil on my dream piece of land and not blink the other 50 would pay for me to hunt the rest of the world
