I was helping a friend do a fireworks show this weekend. We took all the sets of tubes out in multiple trips with my 16x6 trailer and set up Friday evening, only to have the show cancelled by rain. Took everything back in and then back out Saturday and it was a great show. Went back today to pack up all the tubes using the same path I'd used two dozen times over the weekend. But a heavy rain shower hit just prior to our work this evening. On the way out of the field, the very last trip over three days of work, the Expedition just wouldn't pull it out. I had to unhitch the trailer and jack it up off the receiver ball and the Expedition was still stuck. Had to ask a neighbor for a pull. His 4x4 Chevy and a tow chain did the job. Now I have no idea how to get the trailer out and the fireworks tubes have to be returned to the dealer Thursday night. Any suggestions?!?
