1. When cutting underlayment, your wife's scissors from the kitchen drawer
work well -- for about the first 15 feet.

2. Transporting a 15X 30 foot liner in the kids wagon works well -- for
about the first 15 feet.

Unexpected costs so far, one new pair of scissors, one new wagon. I may have
more important lessons after I complete the rocks and waterfall. Stay
tuned.
