Pros:
- organized start corrals
- scenic course after the 10K mark
- great crowds and support
- friendly and helpful volunteers
- the finish line stretch is pretty amazing, i've gotten emotional every time i run down Boylston!
- need more porta-poties at the start

Cons:
- packet pickup is a shit show
- you have to walk at least 1200m just to exit the finishers area, there should be an easier way
- Boston hotels are real f***ing dicks and really stick it to the runners when it comes to prices
