For my first hide I thought I would place it around the Kentucky Historical Society, because there is always interesting things to see, and it makes for a good walk.
You're looking for a small bison tube. Bring your own writing utensil. Plenty of street parking and parking lots around the block to make a quick grab. It is a fairly high muggle area during normal work hours, but most people are on their way to a state office, and pay little mind to someone standing around.
