Please poop on the potty and not your pants

In an attempt to speed this potty training train wreck up I purchased 9 pairs of underoos with cars, toy story and thomas the train on them. We have had 3 pees in various places around the house and one out to dinner at a hot dog stand near the beach. Luckily this last one was at an outdoor joint on decking like material. Too bad I only had a new pull-up to put on him and no extra shorts so we ended up finishing up our dinner of "pronto pups" and fried pickles in the car. Somehow when your child pees on the floor it is much more tolerable than when the damn dog does it. We've also had several poops in the new underwear even though this will make thomas very sad- and mom too who is exclusively dealing with these poops and the clean up. Really, he may not have been ready for all this. He can do it, but the desire isn't there. Makes me think this is going to drag on and on. I don't want to keep switching back to pull-ups, but we may have to for trips in the car and other events that don't lend themselves to pee or poop all over at them. Hopefully the yucky wet feeling will help him get more into telling us before he starts peeing all over the floor.
