(A) No one was killed, although it sounds like the uncle made a valiant try. (B) It's only money. (C) What stories you can tell for years and years. (D) Boo on the guy who screwed up the O-rings as well as the shop for not standing good for the work. A pox on both their houses. (E) Kudos to McFarlands and Riley Ranch. Remember those folks, folks. (F) Might be a good idea to make spare keys to keep in the truck/TH. Just in case brain fade strikes again.
The good news is now you are all set for MORE (slightly less exciting) adventures.
