Behold! The very first Cow Omelets in Wales!
A series started by airhorns in Lancashire and growing fast.
Cow Omelet is an anagram of Welcome to...
The rest is an anagram of the town, but in this case there's a little extra twist...
extract the letters of the town and what you have left gives you a number, save that for the bonus cache, which will be coming later when I get permission.
This is the southern entrance to the town through retail parks, and past South Wales Police HQ.
Suggested parking is waymarked, and you might like to do some of the nearby puzzles as the parking would be good for one of those too.
