I just found this link today. If you haven’t visited Daves blog, it’s the best source of scenery info I’ve found.
Dave Frary literally wrote the book and was a very early suporter of cardstock modeling. As a pro builder he uses what works and what gives him results in the least time possible. And he’s just a great guy who always has a good story to share.
