The best $10 bucks you'll spend
Don't just stare up at The Loop's wondrous skyscrapers, gain a historical perspective with Chicago Architecture Foundation's walking tour. Informative and fun, you'll amass a head full of factoids to impress the folks back home. Take the "old Chicago" tour or the "modern Chicago" one for a measly ten bucks, or go whole hog and do both for $15!
