Children on the playground / DAP again???

I'm wondering whether to attribute today's progress to DAP. Sunshine does not like playground equipment, trash cans, children running amok, strollers etc. Mostly he has reacted to just about everything including the wind blowing and making noise in the trees. Over the last year he had improved dramatically with the things we see on our daily walks. However today we had an amazing bit of progress. We were walking by a local playground that had 2 parents and 2 kids. The minute the 2 kids saw the dogs they jumped off the equipment and were running right at us. I immediately called out that the dogs were not friendly and made a hard turn to the left away from the kids. The parents got the kids back and we continued by the playground. The amazing thing is that Sunshine did not try to bolt, didn't flatten himself to the ground and didn't even look worried. Once the kids were under control we continued by the playground and he had his tail up the entire time!
