Concord has some unique geo features when stripping away the current layers of earth built up over thousands of years. My location for example, is mostly in the middle of a crater impacted by a meteor. There are a few characteristics I noticed:
* Sounds tend to be amplified, as if in a bowl effect. Neighbours conversations in backyards loud and clear.
* Temps tend to be higher in the 'bowl', making summer hotter!
* The stars and sky are clear, as if my location is perfect for a observatory. (just through this in :)
So what does your geo-land look like...find out, you may be surprised.
