I would invest in Commercial Real Estate!

I would like to travel and see the world. Material things don't interest me much :) My Dad always wanted a VW Camper Van so I would buy him that.

HEY OCTAVIA HAVE YOU EVER CONSIDERED DRIVING A HORSE HAWLER? I KNOW A GUY THAT MAKES A LOT MORE DOING THAT THAN DRIVING TRUCK. HE HAWLS AROUND RACING HORSES TO DIFFERENT RACE TRACKS IN THE SOUTH. :O)

Survivalist starter pack. Basically:

Several acres of land (preferrably in a very secluded forest, or a place near a very secluded forest)
Weaponry (both melee and firepower) and ammunition
Seeds, tools and other stuff needed for permacultural lifestyle
Books on topics like survivalism, western esotericism/occultism, paganism, scientific books (preferrably medical books listing cures for various diseases and methods of healing) etc

And the rest of the money I'd give to somebody who would need it, as I would most certainly not need any money if I managed to begin living the envisioned lifestyle.
All of this, of course, is purely theoretical, and it's, unfortunately, impossible to live such a lifestyle in the modern day and age.

You could try to go Amish ;D

I'd ask my dad how to invest it and save it so i don't spend it all and go bankrupt.

How much is the lottery going for?

I figure that I would throw it all into the bank and try to subsist on the interest.

Say one of the PB or MM records of $1.6 billion! If you won that, what would you spend it on?

Adopt a corgi than everything else someone would do if they won the lottery.

I would join the Italian Mafia, and use the lottery money to help get through the ranks.
