The day before I left to help my sister move out from her dorm at UC Davis, I discovered something really cool about my car!
I drive a 2017 Honda Accord Sport, and it has a 60/40 split seat feature which lets you fold down the seats to carry bigger cargo.
Using this feature, I put my karate gear inside both the trunk and back seat. It includes a bo staff and a gear bag:


That seemed to work better than putting the bo staff diagonally across my car’s rear cabin, and I think I’m going to use this setup next time I go to karate!
