Its worth saying as well that although they are generally friendly and happy people, you do need to be firm with them as you end up with them latching on to you "bumsters" as they are known will try and be your guides for your stay. Sound enough people but ever so annoying!!
Terry I think is the guy who runs Dentons and Alan who helps him when I was there. There were also a couple of others who spend alot of time at the bridge and launch their boats from the, one of them was a scouser and I think his name was Peter, nice feller and a very good and knowledgable angler who I'm sure would point you in the right direction. But we met a load of expats there offering to have days out with us, which was very cool and we did fancy a return trip and go right up the river after tigerfish.
My Gambian trip made me think I would be unlikely to book guides again through an agent in the UK.
