LaPorte County
I've been through LaPorte County a few times. My impression is that it is wet. Indiana was left a lot of water by the glaciers, and it is still in evidence everywhere around here and the surrounding counties. There's a Springfield Fen Nature Preserve here someplace, too, that's open to the public and shown on the Delorme Atlas for Indiana, but I haven't got it pinpointed yet. A bit of the Indiana Dunes National Seashore leaks into the county from the west, but check Lake and Porter Counties for that.
