I enjoy reading your write ups DE. There is always a good amount of detail. Just a few times I've had coke but in a bottle. I understand we don't always get the choice though. It's not easy for me to get much down as the bubbles are too lively for my liking.
I'm sure you will learn from your experience & remember to have dry bags with you. Also, you've had the mental demons & not caved in, so you can take some positives from the mental side as well as the physical achievements. You didn't say whether you saw Isaac before his bed time but I do hope that was a happy ending to a good day out.
