We hired two tuk-tuks for our second day in Jaipur. To be more accurate, the drivers hired themselves. Once we got used to the carnival ride / video game aspect of it, we relaxed and enjoyed ourselves.
Several times Tom's driver would come up alongside us and Tom would reach to grab us from one side or the other. It made us jump and it sent our driver into gales of almost uncontrollable laughter, only adding to the excitement.
