Congrats kardell! That is great news! I'm still waiting on financial aid too, but have already accepted so just have my fingers crossed
I figured I could give a little insight on having a car since I've been here for a couple years now. It completely depends on where you live! Any of the neighborhoods near UW (University District, Wallingford, Greenlake, etc, etc) are all pretty easy to handle without a car, by bus, bike, even walking depending on location. Parking can be annoying in a lot of areas of Seattle especially around UW and the Social Work Building. I plan on looking for a place in one of these areas so that I don't have to use my car so much. If you have questions about specific areas (accessibility or whatever) feel free to let me know!
Congratulations again! I hope you get funding since it is your top choice! Best of luck!
