We celebrated Earth Day this week, and I invited folks in for a short tour of Cleveland. For years, Cleveland was billed as the “Mistake on the Lake” because our polluted river used to catch fire. In the 70s, a reporter described it as “the river that oozes rather than flows.” Thanks to regulations, we’ve come a long way. Will we slip back into burning rivers soon? – Traci Purdum, editor-in-chief.
