---------- Hello fellow list readers, I wish to thank the many persons who responded to my post regarding sod roofs. Some execellent references were passed along from the online version of the Avery index of Architectural Periodicals. I also learned of a sod roof which is kept trimmed by goats, and another inherent problem with sod roofs, snakes in the grass. According to one respondent, snakes are attracted to sod bldgs including those that just have sod roofs. I also have a list of resource people who have experience in working with sod roofs on timber structures which I shall follow-up on. I discovered that a considerable body of knowledge and experience exists in Canada, including several sites. Several Forts were also referenced in the U.S. I will happily pass on references to any who wish them. Please email me directly. Again, many thanks to respondents on the list. Now my work begins - where to find the right sod, and the money..... Richard Shockley Director Fort Whoop-Up Centre Lethbridge AB. Canada. [log in to unmask]
