Abstract: A game involving simultaneous moves by opposing players comprises a game board having separate lanes extending in discreet steps from starting positions to ending positions. Player controlled linked gates control movement along the lanes. Players simultaneously select lanes and gate positions and then move through all open gates in the selected lane. Each time a player reaches the ending position, he scores a point and starts over. A predetermined total score wins the game.

Abstract: Vapors of chemicals or minerals in solution, and/or volatile liquids, emanating from a land surface (such as a sanitary landfill) are collected. A first generally cylindrical container encloses the volume of air above an area of land surface, and includes a top surface having an inverted cone shape with a downwardmost point formed by the cone apex. A second generally cylindrical container interfits with the top, inverted cone, first container. The second container is adapted to contain ice, or a like cooling solid or liquid. The second and first containers are of good heat conducting material so that the second container cools the top of the first container. Thus vapors emanating from the land surface condense on the top of the first container, roll down the interior surface thereof to the cone apex, and the condensate drips into a collecting vessel disposed within the first container, below the cone apex.
