River tile graphics question

[witoflash]

Hey everyone!  First I want to say that I'm so impressed with this site, its helpfulness and overall design.  Next, I have to say that no other game introduced to my family (my primary players) have EVER been received so resoundingly as Carc and even all of the expansions.  We are all addicts!

One question though, on perhaps two of the river tiles there is a sand bank? gold deposit? along the bank of the river.  Does this mean anything?  Was it supoosed to mean something?  Am I crazy and should I stop staring at it?  Anyone else care or is my OCD kicking in?

  I think your OCD is kicking in mate. It is just there to make it look preeeeeeety

First off, thank you wito for the compliments about the site, I'm in the middle of a heavy work load at the moment, but when it slows down a bit I'll be adding lots more content.  Regarding the site design ... gosh that's the last thing I'd have expected anyone to say, I admittedly don't have much of an eye for design (or colour, as you can tell) 

hmm gold deposit?  Now there's a basis for someone to use it for their own variant..!
