I've been around for a few days now, but only to catch up.....just seems most people are into other things now.
I found some of your tricks to work really well. I my self used old unwanted hard cover books as ramps, just open them up and let it fly!!!
My last course was made with a long piece of cardboard with 3/8" pieces of wood dowels layed out to make a bunny jump section...pretty cool, if you hit it at the wrong speed you would wipe out.
