2014 Grand Tour Theme

[StarWolve]

Just had another thought... something about "through the years". We always focus on the alphabet, but why not chronological order? For all of these ideas, we could only allow each year once.

Building corner stones - a wide variety of years here. Maybe a bonus for oldest building found during the GT?
Cars - a photo with a different car from each year (Can be difficult to judge when you find reproduction cars though) This one would be tough to put limits on though. A good car show (like the East Coast Grand Nationals) and you could probably cover every year in one day.
Historical markers - Easier on the East coast due to a longer history, but could still be a good one.

Just another idea or two.
