There was a thread in C&V last week about modding the nashbar front rack to make it more rando-style... there are lots of small bags in the surplus stores around here that would be easy to adapt to front bags for a bike with some stiffeners.
Oh I forgot, this
lovely looking canvas bag is my inspiration, I saw a few models of bag I will try adapting and making some mods should be easy enough but the OYB bag seems like a fair price.
