Lonely Planet North American city guides free till February 4

To help stranded travelers navigate their way around a strange city during “snowmageddon 2011”, Lonely Planet has dropped the price on its North American city guides to $0.

The 13 different free guides cover most major cities in the US and Canada and are all available in the iTunes App Store.

You’ve got till February 4 to download and install the apps. As we’ve mentioned in the past, even if you don’t need the apps right away, it makes sense to purchase them now they are free, as you’ll then be able to re-install them any time you need them in the future.
