I'd show Avacyn what the South has to offer:
We'd start by going to Mobile, AL, to check out the historic sites and tour the USS Alabama.
We'd then continue on Interstate 10 to Biloxi, MS, where we'd spend a few days of gambling, fine dining, and being pampered at the Beau Rivage.
Finally, we'd continue on to New Orleans, where I dream of building a life together with her, and spend a few days taking in the sights and enjoying the food and music. I'd have us set up with the Fleur de Lis Suite at the Hotel Mazarin. My angel deserves nothing but the best.
I'd do the driving, of course. Avacyn is very pensive, so she'd appreciate the long drives to ponder things, but we'd also spend some time during the drives conversing with one another about, well, everything. We'd bring our laptops and tablets and a portable WiFi hotspot, and keep everyone updated on our travels!
