Where can I get an extra large satchel/messenger/record type bag?

Try this Briggs & Riley messenger bag (a href="http://www.briggs-riley.com/category/productDetail.aspx?id=Go-Messenger-Bag_VB410" rel="nofollow"http://www.briggs-riley.com/category/pro…/a ) made from nylon. It has large pockets that fit legal size folders, but you may want to check it out in person to see if it can accommodate your lever arch files. The bag has a removable sleeve for a laptop and an organizer section you can put your pencil case in.
