Today I repaired a minor issue in the garage caused by a detonated mortar round.
While having breakfast one morning this summer, I heard the explosion and felt the house shake from the Dept of Defence detonating an UXO in the former Blair military range which starts only 3 houses away from ours. The blast immediately triggered our garage door to open and the light started flashing. We have heard & felt several of these over the past 2 summers, as they have detonated 8 WW2 era 3" mortar rounds and 1 grenade. They have also pulled 2,100 lbs of munitions scrap from the mountain bike trails and dog walking paths in the 640 acre 1930's - 1950's era military training range.
It's rather wild to know that I am routinely riding my gravel bike over this stuff, but in 60 years since the range closed, there has never been one of these accidentally go off.
Anyways, back to the garage. I could not get it to stay closed, and the lower limit adjustment didn't seem to fix it, so I have been leaving the door parked about an inch open these past few months. With winter approaching, it seemed time to take it apart. I found the limit switch was cracked, but was easily replaced and now works fine.
