Presented by Calgary Expo and Downtown Calgary, The POW! Parade of Wonders will kick off this year’s Calgary Comic and Entertainment Expo. It’s free to participate in the parade, but you MUST be decked out in cosplay (costume-play). POW! is tomorrow between 10:30 and 11:45 in the morning on Stephen Ave. Last year, 2 200 people marched in the parade for over 10 000 spectators. (Photo: Calgary Expo)
