I have found just ONE limb up here in BC that i can limbwalk on.....most of our trees are very tall, no limbs until about 80 feet, and the limbs are NOT limbwalking friendly, unless you enjoy hearing a sharp "CRACK!" and then the ensuing swing into the trunk and the accelerated heartrate....
our Oaks and maples are waterlogged dangerous entities, suitable for ascending up the trunk only. Any horizontal limbs you can MAYBE walk on about a foot or two, before they start creaking and snapping.....
Our big western red cedars are choked with limbs, every few inches on the trunk, making for a poor climb....
we got big willows, but the limb qaulity is very questionable.....thanks to our constant rain...the trees have pockets of rot and waterlogged limbs, cracks and twists that crumble into goopy treemuck the moment they are walked on...
argh...i'm jealous of you Southerners, with your big wide spacious trees that are strong and have big fat limbs to walk around on......
I will say that the majority of my climbing has been long vertical only ascents on HUGE douglas firs, with no limbwalking at all. Sure develops the MUSCLES in the arms and legs.....
Lots of traverses, and swinging around the huge trunks.
so, consider yourselves very lucky with what trees you have....its hard to find a decent tree up here...
I recently did a "trunkwalk" on a 4' DBH douglas fir that had fallen across a small river in the recent windstorms. I attached my 150 climbing line to a nearby vertical tree, and used my minigrapple to snag a stout limb across the river, then i walked across, keeping the ropes taut. a very heady experience.......wished i had cork boots for grip.... LOTS of trees like that here, maybe i can develop a NEW tree"climbing" or "treewalking" offshoot....
