Harrison County, MO: Fifteen Harrison County 4-H members attended 4-H Camp this year. The theme for this yearâs 4-H camp was âSwinging Into 4-H Campâ, but there was no time for monkey business as one hundred and ninety 4-H youths from across Northern Missouri converged at Crowder State Park, located near Trenton for two camping sessions June 6 through June 16.
