Potty Training Bliss

I totally forgot to tell you guys this story.. The other day, I am just trying to run two errands... I get the boys in the car, after they have both used the potty and it starts about 8 minutes away from home.. Mommy, I have to go potty.. I can't wait... I can't hold it....I'm on the highway and I exit and pull over into a Kohl's parking lot. I am the prepared mom and have the froggy potty in the backseat. Blake is now sounding the alarm so I jump out and as I am unbuckling him, M starts to tell me he can't hold it and hurry. I throw Blake on a bush and run back to get M and grab the potty. An ambulance is driving through the parking lot. They stop. I see it out of the corner of my eye. Then they proceed to lay on the horn.. I'm not sure if it illegal what I'm doing or not but I really wanted to hide under a rock. Two boys, full frontal and the emergency techs bringing it to everyone's attention. I grab B and pull his pants up and throw him in the car and then go for M. I am still wondering if they consider that indecent exposure.. What's a mom to do? Should have done the Christian thing and shot them the finger....
