Dear Parents and Campers:

As of April 6th, 2020, we are still planning on conducting our Summer Camps, starting June 1, 2020. Obviously, this depends on the progress made against the Corona Virus Pandemic.

I have been in consultation with Governor DeWine’s office. As of today (4/6/2020), June 1st, 2020 has not been ruled out for camps. Obviously, this is subject to change.

All of the campers and parents are in my prayers. Please use common sense in everything you do in these times.

Call me at 513.602.5133 and I will answer any questions you have.

Russ Foster
