I think I would:
- have my current house fixed like new,
- get a new truck,
- maybe get an RV,
- pay-off the lease on my fiancee's car,
- donate money to local shelters and vets,
- donate money to my favorite race track (Talladega Gran Prix, in Alabama)
- sponsor the motorcycle roadracing group that I am a member, or the race school I took, or both
- donate money to schools I attended,
- have some places named after my parents and grandparents

Those aren't really in any order, just when they came to mind.
