CHICAGO (CBS) — Bagpipers and people donning kilts will take over part of Michigan Avenue Wednesday as they walk for a cure for ALS.

The Chicago Police Honor Guard and Bagpipes and Drums of the Emerald Society Chicago Police are joining I AM ALS co-founder and patient Brian Wallach and other ALS patients and their families for the first Kilt Walk for a Cure for ALS research. The event celebrates raising $20,000 for ALS research.

The effort started with a tweet challenge to Wallach to build the I AM ALS Twitter following to 10,000. If he was successful, he was to raise $20,000 and walk down Michigan Avenue in a kilt.

He reached his goal within five days, and now the walk is becoming a reality.
