I've never had it pop up from being left unlatched...  but I have driven
away with it up at least 4-5 times...   Several times just drove out of the
camp ground with it up and quickly realized...  but once over-nighting
outside a casino (stateline nevada) I acutally made it all the way down the
on-ramp onto I-15 before I realized why "it seeemd like there was such a
strong head wind".  Must of been doing 60mph when I realized and quickly
pulled over.

It's quite impressive the wind abuse the top can withstand...
