Day 4 in our 'Twelve days of Aitken’, which is a retrospective look at Mike Aitken’s BMX career as seen through the eyes of some of those who know him best via a selection of his hugely influential video parts, delves into Mike’s section in Square One’s first video “Up In Arms.” Closing out 2001 with another extended stay in Erie, Pennsylvania and enjoying all the newer indoor parks in the area like Section 8 and Shebang, as well as the expanded Buck’s trails, Mike casually filmed his second part of the year.
