...that enables Caravans to have the same trading capacity as Cargo ships? I usually go for TITHES upon founding a religion, which in turn, helps me out on gold as the game goes on. As a result, I tend to build up on caravans to help my fledgling cities get higher population/production, since they're incredibly weak early game. Do you guys think a wonder that would enable caravans to trade on par with cargo ships (i.e., +8 food instead of +4 food traded to your inner-cities) be an effective wonder? Perhaps if it came with a free caravan as well?
