I thought you had tried to get your Eagle Scout :-)
Seriously, congrats to all your obviously outstanding grand babbies. They come from good stock.
There does come a time you must slow down. I can't imagine doing all you do at MY age. You are a trooper. Last weekend I helped build a 40 ft. wheelchair ramp for friends and then the next day I helped the stepson clear his backyard for a fence. That meant trees, several bushes, shovels, axes, picks, etc. I was one sore puppy Sunday and worse on Monday.
