Getting back to your OP yes their has been a increase across the board i have noticed people in the north and south are using them to as the pics they have posted of their trips/meets show. Perhaps people use them in the summer as they would any other tent as they feel they best get the use out of them after paying so much for them as with any kit. i think it deterred when people started to take the **** and made comments that your a sheep if you buy a Lavvu all be it not on this thread. Nobody asked if you liked a tent just if you noticed a increase in the use of a type of tent. maybe they popular as Ray sells one on his site?
