Good find, thanks for bringing it to our attention! I use a similar bag for our family's BOB. I figure 99% of the time we would be bugging out due to some localized, non-TEOTWAWKI event and just need to spend a night or so at a hotel or friend's house. Wheels are much better than strapping it to the back, especially if the DW needs to evacuate while I'm off on a business trip.
