Play tourist in your area. Go see the stuff you'd normally take visitors to see.
Check and see if there's any festivals and such in the area. Or farmer's markets.
Take a drive, discuss your dream house and find a neighborhood for it.
Grab books (knitting, whatever), lounge chairs and chill at the local park/beach/zoo/outdoor restaurant and people watch.
Recreate your first date.
Congratulations, by the way!
