I thought about you and this conversation the other day. I was thinking about jumps specifically. One reason we’ve been going with those long sendy and easier jumps has little to do with the air and a lot to do with sustainability. With every project partner you have to size up their availability and willingness for maintenance. With most soils here in the SW steep lips and landings just don’t work unless you have a group of people continually working on them. This is also why big, solid tables are better than gaps in a lot of cases because that bulk throughout better keeps the shape intact. Trail construction is a lot more complicated than the simple wants and desires of a small few but you probably already know that. The success of any project often has a lot to do with adaptability and working with what is there instead of forcing a vision not based on the actual terrain and soils.
Back in 2005 when I visited Vernon Valleys park that jump line was my favorite, that may be because the rough stuff hurt the crap out of my wrist!
