Peter, I think it would be a terrific idea. Do you think we could get our hands on the necessary pertinent information? I'm talking topo map, with wetlands boundaries, property lines, maybe even current irrigation extents etc? Even if we couldn't, I could always generate most of it from the currently available data.
What kind of timeline are you thinking? (both for starting and for how long participants would have)
I think it would be a much more interesting experience for both participants and the general GCA viewing public than the last contest.
Others, feel free to chime in with some views/suggestions on Peter's idea.
