Ok, finally got to go up on Saturday. They are still making the Mountains in Minutes line. But not alot of it. They have a stock of product. Their main area they now make is polyfoam standing figures. If I had a link I would show you a sample. Any how, Walthers and Sceneryexpress are their two main distributors. The owner, Dave, started Mountains in Minutes in college in his parents basement. They also have a line that is gearing towards WWII and miniature gaming. Along with an Alamo type buildings.
As for the flexibility. It is nice and flexible. They also have a polyfoam line also. Many different types of formations also.
If you have any other questions, I am sure I can find out.
