Here's an observation I made at Trail Days this year:
Along the lane there is this really cool ENO booth. Lots of activity, but people leave asking, "but how do I stay dry? what about bugs?" ENO has tarps, but their booth is all about hammocks. A few spots down the lane is the Hennessy area with three simple pipe stands
and a table. The place is crowded ALL WEEK. You can just see the lightbulbs going off because Hennessy is showing off three hammocks with bug nets and tarps COMPLETE.
Hikers are buying up the Hennessy stock like it's going out of style and he sells out in the first few days and gets forwarding addresses for the rest of the hikers who weren't fast enough.
If I were a cottage manufacturer, I'd go to Trail Days with a complete kit.
