I will have a lot of images but it looks like Powweb has enough room for that. Multiple subdomains is probably the way I will go because I will probably start with information on a few states and then expand as I obtain the information. If I put all the information on one site it will look incomplete because various areas of the country will not be included initially. Also if I create a subdomain for each state or area it will look more local. What do you think?
