4 weeks & I will be in Montana taking photos of pyrex in Great Falls then after that day I get on a plane to go back to Maryland! I'm flying from Great Falls, Montana to Denver, Colorado. Then from there I fly to Baltimore, Maryland. Then I will be in Maryland & will be in Delaware for Xmas & New Years then after that I fly from Dulles Airport (Near Virginia & Washington DC) back to Great Falls where I will then drive home :)
