  1. During last nights storm a tree in neighbors yard fell on your line. We thought it was Avista but they came out this morning & said it was frontier line. The line is sagging closer to the road now. Address is 825 N Tinsmith Lane in Post Falls across from new Midway Auto lot. Would appreciate your swift action.
