This is talked about in terms of bushwalking (rambling, backpacking) but I think it would be useful for bicycle touring as well. I currently use a spreadsheet but I like the idea of building trip lists from the main list. You have even build shopping lists.
I have downloaded it to my Mac and will have a play but thought it worth sharing anyway.
