There will be other posts about my weekend getaway with the big girls to Legoland and Southern California. Posts about how grown-up these kids have gotten, posts about Post-It notes in bathrooms, and posts about how the best part of our vacation involved a night in the hotel.

For now, however, mere hours after we’ve gotten home, I leave you with this demonstration of how I MacGyvered our trip:

You know MacGyver, that fictional character (who headlined a television show of the same name) who could fashion something useful out of just about anything? He would have been proud of the degree to which I kicked ass Friday as we arrived at San Francisco International Airport for our journey to San Diego and beyond.

As we unloaded the car (backpacks for the girls, a backpack for me, and a small duffel bag), I realized I needed to bring their booster seats for the rental car. The seats were within our carry-on allotment (we had purchased three tickets; the girls’ backpacks fit under the seats in front of them), but the girls refused to carry them through the terminal. Instead of fighting with the kids, I furiously searched through my back for something to lash them together. I found three hair ties. That was all I’d need.

In a matter of moments, I had fashioned the hair ties into a carrying handle. The handle did the job—both to and fro.

A total MacGyvering.

I’ve railed on these pages (and elsewhere) about the idiocy of the mean-spirited #CarryOnShame campaign that encourages travelers to shame other travelers when it appears people are violating airline carry-on policies. If one of those people had seen me schlepping the seats around the airport, undoubtedly they would have snapped a pic and shamed me.

In the end, however, my MacGyver move was both ingenious and totally in accordance with the rules. #CarryonShame, my ass.
