Skip Michigan now and just schedule an externship at Leader Dogs for the Blind fourth year. (Agree,
@Rainheart?)
Don't know the logistics, but if you can get your **** shipped and turn the moving into a longer roadtrip with the pup that'd be fun and less horrible than marathoning it all. I keep trying to sell people on Asheville if you end up in the area... enough breweries for the whole trip in one hippy town.
Other than that, travel, relax, read, catch up on games for sure. If you have any hobbies you've always wanted to try or have dropped off the radar, pick'em back up. Even for the most type b people vet school is stressful, try and start very chilled. Just be happy for a while and revel that you got in.
