If we can get the mids in Rome with only 2 chops, I would be for that. I don't see the reason to build it in fish city, other than to save the forests, and even then only 2 forests isn't that big of deal. Forests can regrow, so we can try to chop the forests that border multiple forests to increase the chance of regrowth. Mids in Rome is a building, and counts for the wonder count. Remember we need 7. I would hate to have to go for a wonder after the Taj, as there isn't too many before we get to later expensive techs, like Democracy for SoL.
