I'm making a campingguide and I need to have a menuitem that fetches all the campingplaces that is open in the winter. So I make a category "Wintercamp". But I also need to make a menuitem that shows all the mountaincamping places. So now I have a camping site that is open in the winter AND is on the mountain. So since a campinglace can be in only one category I wonder if someone have a suggestion to how I can solve this? I can use keywords in stead of categories, but I can't create a menuitemn for a keyword? I need to create a menuitem URL (SEO stuff).
