Alnwick Castle in Alnwick, UK. (pronounced "An-nick") We were blessed with a gorgeous day and very few visitors when we first arrived. As we were leaving, several large tour busses filled with Japanese tourists arrived. These shots would have been impossible after that.
And if I haven't said it enough already, the 24-105 is hands down the best walk-around lens on the market.
