I want to get one of those bags that you carry across your chest. Slung over one shoulder. Not sure what to call it. Something like a bike messenger bag. Subdued color. I want to carry: small trowel several books in dry bag canteen poncho fak pruning shears, small And most importantly have room for small/medium amounts of foraged roots, leaves, fruit, nuts or whatever. I plan to carry this to forage in local parks, cemetarys, greenways, ect -- so I want to blend in to the urban scene and not make it obvious what I doing. Any suggestions would be appreciated.
