I've hit a concrete sanitary sewer in Pendleton one day...
I've hit a residential natural gas line just outside I-69 in Ft. Wayne one day...
I've hit a water main outside of Madison one day...
And I've hit a big fiber optic line up somewhere in northeast Indiana one day...I think it was SR 2 between Lowell and I-65. Saw the line insulation come up out of the ground and was...."uh oh". Kept working. Actually hit it twice - about 100' apart. That was fun.
And I've made some folks MIGHTY nervous as we were working close to a LARGE trans-continental petroleum pipeline on US 224 out by Belmont HS in Decatur. Our equipment was still a few hundred feet from their stuff but they still sent out people to be SURE that we wouldn't impact their stuff.
Best part about all of the above: Not my fault due to faulty, incorrect, or plain missing utility location marks.
