You're right. In fact, the fogged tile in the mountains has 3 food resources and silver. Another reason not to rush camping the deer - we might lose it for a while early on if a creative civ is below us.
Is there anything specific anyone would like me to experiment with in a test game tonight?
I lost the deer for a couple of turns on my map, so we must be prepared for that.
We're just trying to decide if we're going for the pyramids or not. So if you want to try the pyramid track on for example my (modified) map, I think that would enable us to take a better decision. It's just a suggestion though in case you have spare time
