Brett,
I just wanted to give you an update on my project.  I would like to go out to the prairie starting sometime soon, maybe in a couple of weeks weather permiting, and start to map out the squirrels' burrow system.  Please let me know if there are any times or dates when you wouldn't want me on the property.  Also, if you ever would like to come out and see what's going on I think that would be terrific.  Last summer the dogs on the property discovered one of the traps and unfortunately killed the squirrel inside.
Do you have any suggestions on how we might be able to keep the dogs from getting at the traps?
