I had found a deal on the net and I don't work for or anything with the company but I wanted to give you guys a heads up on a bag (the Osprey Space station 140) http://www.backwoods.com/osprey-packs/spacestation-140.html
This bag I just got in today to replace my existing long range BOB that is designed to be mostly traveled with by car or bike with trailer. It has the capacity to be wheeled down trails and is very durable with large capacity. It's purpose is long evacuation movements. Anyway they are trying to get rid of some inventory and they dropped the price to $130.50 when you click to select the item. I had originally e-mailed them thinking there was a error on their website but they informed me it was a inventory reduction sell. I don't know if anyone is interested in one but I thought I would give you guys a heads up before it goes back to $250. I wasn't sure if this was crossing the line on reporting sales that we find while not working for the company but reporting it for others benefits, if it is please delete this thread. Anyway good luck to those who get one, I can vouch for this bag, you will be pleasantly surprised at how good this bag performs.
I had forgot to mention it is people friendly lowering your signature profile.

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.

Osprey is a terrific brand.

I have one of their backpacks.

That was a nice deal, unfortunately it seems to be back to the regular price as of 7 pm EST...

Thanks Blast and sarbound it's still at this price at 8pm est, you have to click select color and sizes to see the discounted price. I bet these won't last long because they are under the price that they are buying them. They are trying to get rid of surplus inventory. Lifetime warranty and a great durable pack at that price is awesome.

+1 on the wheeled duffle bag idea. Lots of room and no weight on your back. You might even add a wheelie bag for each family member.

If you want a large wheeled duffle bag, go to the ice hockey store and buy one of the jumbo-sized ones meant for goalies. The things are huge!

a $15 luggage dolly will serve the same purpose.

I think the wheeled bag is certainly a good option but I also think a backpack and a plan for pairing down to just what you can carry in the backpack isn't a bad idea.

A good used golf bag could be very useful - replace the bag with a good larger backpack and a cargo tray. These bags are designed to be wheeled over ground.

One caveat - ANY wheeled bag will leave easy-to-follow tracks......
