My idea is this - sign the physical log as normal but in celebration of the great TLA please consider logging online thus...
Presuming we all have a car (or 2!) & they are new enough to have a reg plate ending in 3 letters.
Use only a 3 word phrase gained from those last 3 letters or make up 3 if you don't have a car.
This way I'll end up with a log list of random words to keep me amused
For example my log would simply read: Zebras Love X-rays
**Once again this is all entirely optional & all other log types will NOT be deleted**
You may also add a note if you've a story to tell!
Finally there may be parking for a couple of cars when it's not busy so could be a drive by - I would avoid school drops times
Many thanks & happy cache-ing
