DenverInfill is a geeky love letter to the city of Denver -- a nostalgic testament to what it once was, and a joyous celebration of what it could become. Ken Schroeppel, urban planner with Matrix Design Group, has created a comprehensive and interactive guide to all infill development proposed or completed in and around downtown Denver. Through vivid maps, clear charts, a colorful blog and such creative forays as photo essays of LoDo's remaining painted commercial signs and a mix-and-match guide to cheesy subdivision names that lets you churn out such stinkers as "The Dominion at Buffalo Gap Knoll" or "The Sanctuary at Thunder Brook Butte," Schroeppel takes the obscure topic of urban planning and makes it understandable, even exciting. You grow, Ken.
