First would be to pay off my mortgage.
Second, I would buy a really nice sports car. Maybe Ferrari, Maybe Porsche.
Third, take the family on an amazing 10 day vacation to Walt Disney World, two bedroom suite at the Grand Floridian and no worries about the obscene cost of food and crap inside the parks.
Fourth, put the remaining change in the kids piggy bank.
Now that the mortgage is paid off, my wife and I could afford atleast three trips a year to PDC without any kids.
