Hi Millhouse, maybe i can help. The river moselle is quite a good start but there are one or two good carp rivers nearer, what about the Marne ? All the French rivers hold carp and it is very exciting fishing. Best bet is to have a look on my website then get back to me if you have any specific questions as it is very much an open question as there are so many options available to you.
