I'll send it in a note.

I have an old trunk with dog items near the back door, but there is a mysterious/occasional leak when we get rain. I have moved the trunk a few times with it on a piece of cardboard, but when that gets wet I don't want it soaking into the trunk. And the little knobs at the bottom of the trunk leave lines on the tile floor. So today I'm putting together a few boards and castors to put under the trunk and make for easy moving. I still haven't figured out the leak, but have ruled out a few guesses.
