Subject : RE: List of items for cost comparison

 For those who are looking for a list - take a look at this one.

My first cut.  After I work on this draft, with whom ever wants to contribute, I will send out a completed table with all this included.

If you wish, please add you ideas in CAPs and forward back to me directly. Simply select forward, drop in my email address, do your edits and send.

If you have a cost estimate prepared for a roundabout or signal, pass it along directly so I can pull off some ideas. I don't need the dollars/hours, just the items.

Thanks
