This is strictly a guess, but she/he might be talking about the Mid River Drive commuter lot. If I'm right, the coordinates are 38.80100N and 90.62122W. Sorry, but you'll have to do your own conversion. Happykraut >> ummm what cave springs lot.....because I live with in walking distance << Commuter lot, north of 70. Coords and map are on the event page at geostl.com. Jen
