Utah - I live here. I quite like it despite the many joaks we make of it. Moab and the Arches National Park is one of my favorite places to visit and I try to go there at least once or twice a year. A lot of the natural hiking spots and mountain regions are just amazing. I just wish the state wasn't in the form of a Bethesda map where there is absolutely fucking nothing between the major cities.
Nevada - Went to Wendover. Never been to Vegas. It was still pretty fun.
Arizona - Went to Mesa originally to visit Footsies but ended up going to a MNF game instead where me and Mr. C watched the Jets get absolutely massacred by the Cardinals. It was ok, but incredibly hot. Especially for the middle of October. Mr C absolutely despises it for some reason, probably cause he got yelled at for jaywalking.
Colorado - Spent about a month there for my ASM training at Walmart and drove through a few times since then. By far one of my favorite places on the map. Fucking gorgeous. I really want to go out there for a week or two in the summer if I can get someone to want to do it with me.
Nebraska - Drove through, but we did stop at the Great Platte River Road Archway to sight see. Other than that, it felt like it took forever to drive through and was mostly just boring plains the whole time.
Iowa - The only thing I remember about Iowa during my drive through is that there was about five or six wrecked trucks on the side of the road.
Illinois - I got pulled over here for having a scented tree hanging from my rear view mirror as I was apparently "hiding the scent of something". It promptly turned me off from visiting Chicago or anyplace else.
Indiana - Stayed overnight here twice. It was pretty eh both times.
Ohio - Went to the Rock and Roll Hall of Fame in Cleveland. Really enjoyed it. Surprisingly cool place.
Pennsylvania - One of my favorite places to go, especially when I was a kid. I loved camping out in the Poconos.
New York - Pretty much has everything there is to offer no matter what your hobby may be. I'm not a fan of NYC but Long Island is incredibly. The Catskills and upstate NY in general is really lovely and I do see myself moving back there years down the line. I got very homesick when I was visiting there in May. There's nothing quite like it.
New Jersey - Went to Six Flags Great Adventure in Jackson. We stayed at a hotel that smelled like mildew. It was fucking gross. And the factories along the highway smelled awful. Palisades Interstate Parkway, however, is the most beautiful highway drive I ever been on.

I went to Logan for a date last week and may as well have been in Idaho.

Colorado is probably my favorite next to New York.
