Jeff is A M A Z I N G, we did a bike tour with our daughters (10&12) and had the best day. Not only was it super fun [and felt extremely safe] we learned a ton. Jeff's knowledge of DC and his love for the city and history is inexplicable. If you are reading this review it is because. you are contemplating this activity, don't over think it just book it, I promise it will be one of your family's favorite memories of visiting DC.
