The Mega Millions jackpot has topped $500 million and will just keep growing until the winning numbers are pulled on Tuesday night!

If you're the one left standing with the lucky ticket, what would you spend the cash on? I've had a dream of building my own backyard roller coaster since I was in elementary school. Combine my love of coasters with an idea I got from a Sweet Valley Kids book, you have a woman in her 30s still believing that dreams do come true! But, let's be honest.  Roller coasters aren't everyone's cup of tea.  Maybe you get motion sickness and rather buy a HUGE house with your winnings.  Check out these 4 HUGE Boise mansions you could afford with your Mega Millions winnings!
