Alligator Storm Drain Count

The Mayor's Bicycle Advisory Committee wants to collect data on "alligator" storm drains in Baltimore's streets. What's an "alligator" storm drain? It's a drain with the slots running in line with the road, such that if your wheel drops in the slot, it will "eat" your wheel. Please send me an email (RBruckdorfer@gmail.com) noting the street and location of the drain. Example: My street, west bound in the 600 block or note the address closest to the drain or between such and such streets.
