The 23rd annual Trinity Catholic School [map] Cow Plop takes place tomorrow (that is, Saturday, June 1) from 11am to 4pm.

For the uninitiated, a cow plop lets cows do what cows do best while humans gamble on the deposits. The top prize is $3,100, and there are 50 more cash prizes to be won.

In addition to the live bovine bingo, there’s a street carnival with face painting, a mechanical bull, pony rides, arts and crafts, and pizza from Pizza Rita. The event is open to everyone, not just Trinity students, and is a great way to help raise funds for a neighborhood school.

Bingo tickets are available in advance or on the day. For more info, call (509) 327-9369.
