same thing, different trip

Why does packing for a trip always sneak up on me? No matter how much I think about it in advance, I can't seem to actually begin packing until the day I need to have the car packed. It gets old, but I can't seem to begin sooner. We are going on pretty much back-to-back trips this month, and I know it will be crazy insane transitioning between the two. We are headed to Myrtle Beach on a ranch-wide trip, and then we will be home for 3 days before we leave to hang out with Allen & Andrea and our nephews at Kiawah Island, and I know those 3 days will fly by and then I'll be packing again rushing to get done. Ahhhhhh!!! The insanity!!!
