Abstract: A field assembleable wildlife observation shelter having an assembled configuration as that of a naturally occurring environmental element is provided. The shelter, which is modular in design, includes a plurality of rigid wall forming panels. Each of the rigid wall forming panels of the plurality of rigid wall forming panels has perimeter edges, and an arcuate cross section. Opposing side perimeter edges of each of the rigid wall forming panels are adapted such that adjacently paired rigid wall forming panels are reversibly securable in furtherance of forming a wall for substantially surrounding a wildlife observer. The plurality of rigid wall forming wall panels are configurable so as to form a transportable stack, more particularly, to define a secured bundle.

Abstract: The invention provides a railroad car adapted to transport bulk commodities such as coal, mineral ores, or the like yet efficiently and safely haul bladders filled with flowable commodities. The railcar includes a rugged bracing configuration which enables the railcar to readily transport bulk commodities in standard industry volumes, and within existing industry standards for material handling procedures such as flood loading of coal and rotary dumping of coal cars. The bracing configuration, floor layout, and car dimensions also permit the use of a maximum volume of bladders for effective hauling of materials in such bladders while avoiding undue wear and tear on the bladders. The bracing generally consists of at least one brace including a lower horizontal strut, an upper horizontal strut, and a generally vertical strut member. The bracing allows the railcar to handle bulk commodities such as coal while eliminating surges in bladders filed with flowable products.
