The Johnson County Card Show throws its Halloween Bash at the Homefield Olathe Training Center on Saturday and Sunday, October 31 and November 1, 2026. Holding a two-day show on Halloween weekend is a bold call, and the Shake and Bake Sports Cards crew leans into it — costumes are welcome, the atmosphere is looser than a normal Saturday show, and the room usually picks up a family crowd in the morning before trick-or-treating takes over the evening.
Saturday, October 31 runs 10:00 a.m. to 5:00 p.m. Sunday, November 1 runs 10:00 a.m. to 5:00 p.m. as well.
Admission is free on both days.
Vendor lineups, table pricing and the December schedule are posted on cardshows.io and on the Shake and Bake Sports Cards social channels in the week leading up to the show.
