Hmmm... well, I'm stuck at work, but if I COULD...
It's a magnificently gorgeous day here in PA, so... I'd hop in the car, open the sunroof and windows, and thoroughly enjoy the country roads along the Delaware River leading up to a beautiful grass-field airport in the hills a bit north of here... and have a nice picnic watching the sailplanes and biplanes taking off and landing.
Then pop off to the nearby park and hike the trails, taking photos of every beautiful thing I can find.
Maybe stop for Thai food for dinner on way home.
Snuggle on couch, and catch something on Pay-Per-View (if you haven't seen "V is for Vendetta" yet... highly recommended).
This would be a most excellent day
