Welcome, Matt! Glad you find the right forum. You probably already found it, but you will also find general discussion in the MMMBA part of "MMBA Member Organizations" one level above this. In there are many threads discussing more specific things for our local area trails, including Burchfield, Anderson Park, Rose Lake, Bennett Park, Ella Sharp, Sleepy Hollow, etc.
Some of those threads are even for individual stunts, including the new one on Hansen's:http://www.mmba.org/forum/viewtopic.php?f=40&t=118799
That thread includes much more detail about the stunt, if you're interested in seeing how it is being done. Work has stopped for the moment due to the mosquito density - I don't really want to be standing basically still for hours on end in a muddy area at Burchfield right now! I will be posting updates once I get going on it again.
