Ooops! Needed to pull the hopper bottom today and thought I would just drop the tanker over on the pad. I've done this loaded before but never on this pad, I had even loaded off of the front one time and it was only WATER so I really had no concern. Turns out that pad is only about 2 inches thick and really old plus we have been very wet lately so I'm sure the ground under it would be soft with the river up. I opened the valves and let it all out so tomorrow we can take the backhoe and lift her up to see what we've got.
