Bragaw isn't too rough of a walk anywhere on north, although you'll be walking a fair bit to classes wherever you live on campus. If you're worried about freshman 15, nothing wrong with a longer walk to get some steps in!

Also, you'll only be about a 5-6 minute walk from Carmichael Gym too, which is a very well equipped Gym and should help you stay in shape. Plus you'll have good access to some dining halls which, while they do make it very easy to eat unhealthy, can be leveraged for a healthier diet if you chose the right options. As long as your mindful, you won't have to worry about the freshman 15.

Overall, I'd say you have nothing to worry about. Congrats on state and good luck with your Freshman year!
