Background doesnt show up behind the main masthead
Remove about 20 px of padding at the top of global cities section
The city event list should probably be one event per line.
Shore up the spacing on the left and right side of the city slide to be even. It seems the right side of the list is closer to the edge of the screen
Maybe consider truncating the list a bit to only include events that happened in the last year or are planned for the future.
Description section. This wording is poor. We should rewrite or consider dropping it.
Sponsors. Lets put these in 2 sponsor squares per line.
Call to Action button text is cut off due to the smaller screen. Should change the wording on mobile or make the text much smaller
Speakers Section. We should go with one of two options here... Keep the 1 speaker per row but center them on the screen. Currently they sit against the left of the screen (not sure that is happening since bootstrap shouldnt let this happen by default) OR we move these into a slider where you can use touch to slide the speakers off the screen like a slideshow
