Well done both! My own scheme has one letter different to Richard's: Hidden Text: I missed the alternative abbreviations as cited by Para (and Richard). So I guess Para should be the winner for that thorough walkthrough and for finding out all the possibilities. No disrespect to Richard but I'm sure you don't mind giving somebody else a chance once in a while.

Of each die, at least 2 faces must be used purely as the first letter, and at least 2 faces must be used purely as the second letter. |

I do not agree, rain in England as in Bretagne or Normandie in France is still possible in June . As for cold, ask any mexican and it is still cold some days in June!, I have tried Canadian summer and it is really Mexican winter !Now lets wait for Para's puzzle... and European summer |
