Hotz Mats now offers weathered felt roads:
From their announcement:
We had a number of customers request weathered roads because they felt our current line of felt roads were too new looking. We now have weathered roads available, although due to the heavy volume of Christmas orders were are receiving at this time, these are not currently listed in our purchasing pages. To purchase, just send us a price request to: firstname.lastname@example.org
Our felt road systems are inexpensive and give you a lot of product. With our 6mm roadway set, you get 27 feet of roads (2 inch wide); our 25mm roadway set No.5 gives you over 33 feet of roads (6 inches wide). Both scales of felt road are available as weathered roadways.
