Yep. The Ultimate Packing List. I've been using it for many years now. Saved it to my computer and customized it (deleting what we never use, adding other stuff). Print out a copy for each trip and tick off items as they're packed. Best tip I ever got was to throw the packing list into the suitcase. Then use it again when you're packing up to go home. Much less likely to overlook things that way.
