well, we started on wider ladder bridges built low to the ground, and worked our way to the skinnier ones, then started elevating things.
it's all on private property, so there's no issue of "tree cops" getting mad at us. Besides, we don't use live trees.
yes indeed, we ride it at night, even when it's wet, icy or snowy. our little "Winter Olympics" is coming up in 2 weeks, and we will have a "night lap" event in which we're timed completing a lap at night.
if you ever come up here in the non-skiing months, I can probably arrange for you to visit the Fran-Dan. guaranteed fun for the whole famned damily
