This is a fun bike ride! The Aerojet facility is an abandoned former solid rocket manufacturing complex from the Saturn V project. There are numerous buildings and lot's of urban blight but it's a really interesting day. It is NOT recommended for skinny tires and I would strongly advise bringing an extra tube as there is a lot of debris around. It's around 13-14 miles to cover the whole site. http://www.abandonedfl.com/?p=627
