My thinking with waiting a bit before settling a second city (and it wouldn't be too awful long anyway) is that I've read various threads and such where someone has run simulations and found out that its better to let a city grow a little bit and then pop out settlers. While it delays starting the settler, long term it is better. The exceptions tend to be a race for copper (when the resource is near a neighboring AI civ), or if there is a nearby settling location that would be an early worker/settler farm and eventually transition to a GP farm. We dont have that scenario here. All that said - it is just a thought. I'm certainly amenable to the idea of pumping out a settler earlier. That was part of the reason why I stopped when I did - because no were committed to the next build - so there is nothing to be lost by switching. I'm a fan of stonehenge. I like not having to build a monument to accelerate border pops in new towns. Also, with our traits being protective/charismatic - I believe we get 1 free with a monument - making it doubly useful to us. Which tech unlocks SH? Was it masonry, or is it mysticism. If myst, then I'd say switch from AH to myst and unlock stonehenge, then go after AH.
