For those floating the next couple weeks:
ThermaCell has a "mini lantern (2006 model)" that has been discontinued everywhere other than there website that is recommended for higher elevations. All reports are these things do a reliable job of creating a 15x15 foot area largely free of bugs. They are selling 2 for $12 on their site, though its $7 for shipping. Seems like a cheap option if you don't have room for a screen shelter (like us). Evidently the other models struggle to work do to their lighting mechanism and this one is manual.
I will have a review of their function when I return July 5th. I will also let folks no how the "Original Bug Shirt" lives up to its reputation. Going loaded for bear and hoping we don't need half of our bug ammunition.
