But, to start with, here are a few pics from England. I would highly recommend London in the Fall -- make sure you bring an umbrella, raincoat, and amazing walking shoes (I got these and though not waterproof, they were great since they were lightweight and dried quickly). London's misty rain is no joke. It gets cold quickly when it's wet, even in the beginning of October.
See some of the pics I took in London with my Canon 70D and Canon EF-S 17-55mm f/2.8 IS USM lens below.
