So I rode a tandem bike around Stanley Park and it was hilarious!! It was pouring rain ten out of ten vancouver rain! We couldn't have cared less misery loves company and we had two sets of tandem bikes! Highly suggest this, not because its cool or bad a**, but the exact opposite! It made it so much fun and hilarous all the way around.
