218 chucks, that's a nice pile! Have heard that Pa. is loaded with them. Seems that no matter how many holes you find, a few always get missed. Every check seems to give up a new hole or two. Checking early and late in the day at feeding time sometimes helps. A startled feeding chuck running for cover will sometimes lead you to holes you might not have found without their help. Along the edge of the thick stuff look for subtile parts in the grass, packed down grass muddy prints on the grass itself that often gives up additional holes. With clusters of holes, 6 or more, it usually speeds the process to fill half of them, at least, from the start as there is rarely a time that each hole represents a chuck.

caught the problem chuck this a.m. by the swimming pool.12 lbs!!

Always remember when thinking bombs the distance from the home or structure. It is a bad feeling when you see smoke coming up from the ground next to the foundation.
