Hey! Rumor has it you know of a transformed military base that would make an awesome case study-or an unoccupied base, bunker, or bomb shelter that needs some TLC. We'd be thrilled to add these to our litany of successful (or failed, or just plain blah) precedents and prospects to the Challenge's resources.

To make your suggested site as useable as possible, we just need a few details from you. That's why we pulled no informational punches on this form. We hope you spend the time to enrich the Challenge with your contribution. Together, we can document and map a world of untapped potential.

Thanks. We'll see you on the parade grounds!
