"special" one time competitions scheduled for this spring/summer/fall

So what is going to make these competitions so "special".  Well right now we are working with a third party to promote the Boston Mad Dash for a one time discounted event through their company.  What makes it special is that again it will be discounted and will be open to the public.  The only catch is, that you must register as a team of a minimum of 4 to play and we will not be providing cameras for these 3 dates you must bring your own.  There will be only 3 dates for this type of event and we are looking for a big turn out on each (spring, summer, and fall). For people that have played The Boston Mad Dash before it will not be the same game there will be 4 challenges instead of 6 but the will be fun and wacky as all our games are.  We will announce what those 4 challenges soon as well releasing the dates and the company we have joined forces with to promote these "special" events.  We are also looking to announce "special" competitions in Chicago, New York, and Philadelphia .  We will keep you posted.
