Well if I cannot find a fish and lumber trade, then I guess we could let you join. The fish trade is not necessary for the 3BR, however, the citizen boost (8%) is one of the factors that makes it really good. Silver is ok, but I have always seen the 3BR mostly with a fish trade. Thanks for responding!
Also, Alden Peterson, If this circle can be made, you will need to buy a harbor to get the fifth trade slot. Just incase you didn't know.
