We got the slackline up again on our deck and I’ve now invested a new way to “time deepen” and multi-task…slack line gardening! I just noticed the sign in the back says “falling” and enjoyed a good chuckle because there was lots of falling as we tried to get this shot!
TA Loeffler's Adventures that Move 
TA – what is your slackline tied to? That’s quite the shot! I don’t have anywhere in my yard to hook mine up.
The anchor is a piece of webbing that essentially wraps the decking…and then I rig some mechanical advantage to pull the line tight-we use a motorcycle stand and crates to prop up the line. There are lots of plans on the internet for setting slacklines without trees…indoors even.
I’m impressed, TA!
