I'm still leaning on getting GLH. However, BIC's post makes me reconsider tech path to Fishing>Writing. What does this accomplish? Simple: we get to see the land with warriors and have about 20 turns more of information to help our decision. It might push back GLH a few turns but by the date we're already looking at to get it, it probably won't change much. Moreover, we might find a better site to build GLH - that is somewhere with trees! Combined with Mathematics, 260 hammers is only 8 forests and a few turns... granted it doesn't look as if there are that many trees around but maybe we can look with Flying Camera a bit more. And if we elect to skip GLH, well that's the tech path we would have take anyway. The second city can put some hammers on another workboat (clams) or a warrior for scouting or the library... all 3 are good options.
