We close on the house on the 15th of October, and I should be in Michigan by the 18th. The first set of buyers backed out of the contract three days before we were due to close. Worst part of the deal was we were under contract for 48 days, and when they backed out the height of the home buying season was over. I'm moving to Grayling MI. It's expensive as hell to live here, and more and more people are moving into the area. We're currently about 20 miles south of southern DC in Waldorf MD. I'll be terribly happy to see the Metro DC area in my rear view mirrors. I'm also semi-retiring as part of the move. Can't wait! Chevy Chase is a nice area, but it's even more expensive than where I currently live. ;-) Mark -- One Man, One Machine, One Computer! <VBSEG> ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
