Prediction: Boy never took off in balloon, but may have tried. Seems doubtful that the balloon would be strong enough to lift him, yet would only go to 8500 feet and sink so quickly without him. Here's hoping he's hiding from dad because he lost the balloon.
Getting used to the new MBP trackpad is going to take time. Not having a dedicated button is throwing me off as I typically keep one finger on the pad and another on the button; never removing either when not typing. This doesn't work so well with the new trackpads.
