Popping a squat

Potty training is one of the more difficult tasks of parenthood, or so I am told.  My daughter likes to dress herself and quickly discovered the enjoyment of picking out underwear to accessorize her outfits.  We did very little work to train her.  However, there are always bumps along the way.  One major bump that has come up twice is what to do when you have no access to a potty.
We were at a park this weekend with no potties in sight.  Leaving the park was not an option to consider since that would have resulted in a major meltdown and a child who would then refuse to potty.  I believe there are certain skills every female should learn but would have likely deferred instruction on "popping a squat" until later in her development.  However, desperate times call for desperate measures.  Fortunately there was no one else at the park to judge my choices as a parent, except my husband who captured the moment on film.  Unfortunately, my daughter's aim wasn't straight down.  We had made the critical decision to remove her pants, underwear, and shoes prior to squatting which paid off, as there was urine streaming down her leg.
