I'm rather new to cycling so please forgive my naivety. I am considering going to Philadelphia this weekend to see the third leg of the Commerce Bank Triple Crown Of Cycling but I've never attended a bike race before so I'm not familiar with how it all works. The race's website doesn't give a whole lot of information other than that VIP tickets are available and a course map. I assume you don't HAVE to buy tickets, but can just go to a spot on the course and watch. If anyone is familiar with the Philadelphia race and could give me any guidance (the best roads to take to get to the Manayunk wall, a good place to park, what time you have to get there to beat the crowds, etc.) or any other resources, it would be greatly appreciated. Thanks.
