Spain starts with F LIS and A MAD
France has a F NAN which borders BOB and ECH
Holland has a F HOL that borders ECH and NTH
Britain has F LON which borders ECH and NTH
When I put I40 together I pondered over this area. MOR started as Spainish territory, and there was originally a land bridge between CAD and MOR, but it seemed Spain grew to fast right out of the gate with such easy access to N Africa - which is how it got where it is now.
Revisiting it, and reading the opinions so far - I don't think taking away WME connection to BOB and CAS is worth moving the border.
