This may sound really wierd - but I have read somwhere that avid christmas light lookers will make up a postcard type thing and when they see a house that is exceptionally well done they will fill out the card thanking them for the experience and either drop it in their mailbox or put it in the mail. I think it is just a way of showing appreciation, etc. In fact I think I originally saw the idea here on the boards! Someone might be able to tell you a little more about it. I think that would be very economical to include in your baskets. Also are the people that you are making the baskets for all in a similar area? How about including a detailed map(s) of the known "hot spots" to look at lights? You can always photocopy the maps, again making it very reasonable. Good luck with your baskets - this is a really cute idea!
