-roll your masts up into your sail..
-insert your extension into the boom head
-rest the sail/mast on the extension as if on a rack
-use the downhaul line to lash it secure
-thread the outhoul line through the clue grommet to secure the back of the rig
-wrap your harness around the middle
-carry it by one of the boom arms and carry the board with the other arm

I use this method to do about a 5-10 min hikeb through some pretty tight paths and it works great! the backpack method looks awkward to get through tight brush because the board is across the path. be suree to post some pics if you invent something!
