Leo (TopCliff): Thanks, though I think more applause should go to the NHP for the amazing map!
blade2k5: Wow, the actual creator of the map! It looked like a great map to work with, so I had to try it.
Update 1: Agriculture and More Farms
So I noticed that there was a bit of empty space between some of the houses near the church, so I decided to put a small ploppable lake there. After removing the trees (and activating the grid), this is what the area looks like.

Of course, every ploppable lake needs water! Though first, I had to lower the area it would sit in.

Then came some details to surround the lake, and a pathway so sims can enjoy it.

Add some trees back, and there's the finished product.

Here's a zoom 5 shot of the lake.

Here's some extra zoning, including a cow farm and a few more houses.

...And here's its developed form.

And then I took on some of the land north of the railroad, adding three more farms, some housing, and a small commercial area.

...And after the click (well, after a few clicks, as some of the farms were less than satisfactory... remind me to clean out my plugins soon).

And here's the status of the town after Update 1! Thanks for reading!
