I have now been stuck on 27 for ages. Therefore if anybody knows of a legal number plate which lives nearby them, and is no further than 100 miles from Hemel Hempstead, I will offer to buy them drinks, on the successful completion of me spotting it.
Leave details in the comments box.
Hunt now off, after Heather helped me spot one earlier.
Now time to find those 28s and 29s that have been teasing me.
