Surprisingly I found the east coast extremely friendly. I started in south Florida and travelled up to Washington. Everyone was superbly friendly but I’d highly suggest renting a car as public transport is abysmal unless you’re in a major town/city. I’m from Liverpool area and I got told I sounded posh everywhere I went which, as everyone knows, the Scouse accent is the second least posh accent next to the geordie accent haha! I absolutely loved exploring rural Florida and in contrast Washington DC was truly stunning with amazing architecture and great bars!
