When on the Events page it can take awhile for all the events of one month to load and the best way to counter this is using the region filter. The region filter however is not very user friendly as the only ways to navigate it are by scrolling through the list or searching with CTRL+F (which should not be relied on as a feature for numerous reasons)

The best solution to this would probably be to have a search box at the top of the list. Mobile users can tap on the box to bring up their keyboard, meanwhile, any PC user can just begin typing and it searches for regions containing the string.
i.e. typing "FIM" would yield "FIM - First in Michigan" but typing "Michigan" would yield "FIM - First in Michigan" and "MIHIS - Michigan - HIS"

The alternative solution (which could be done for the short term) would be if the drop down is open and the user types a letter, they're taken to the first region with the same first letter. i.e. 'N' scrolls down to "NC - North Carolina". There's plenty of different ways this version could be implemented and any of them would be an improvement from how it currently is.

The first option would be best because it is user friendly for all devices especially mobile, but trying to make it fit in naturally would take far more time than the alternatives.
