If this was a mormon (or mormon sponsored) troop, there would NEVER have been a Sunday Scout trek. Surely you are mistaken.
I wan an adult leader in UT for about 5 years before moving to TX. All the summer camps in UT started on a Monday and ended on the following Saturday, so the boys only got 6 days, and were home for Sunday church services...... I was also a volunteer leader in TX for about 6 additional years. There the camps started on Saturday and ended on Saturday. The mormon troops would not come until Monday, so their boys only got 6 days as well instead of 7.
