I can’t say much about the LA intern life since I worked as an intern at NYCDOT, but remember to bundle up before you head up north! NYC can be oppressively cold in the wintertime. I also bought an older version of a NYC NFT guide which I remembered absolutely loving, but this was before I purchased a smartphone. I’d also recommend getting a Citibike pass when it starts to get warmer–it’s a lot more fun than the metro and will probably save you money!
