To get the map you need to "add a free form field" to your profile and then create the html code to reference the map image. I got mine at the site below. My html string (for my state HPs) reads as follows:
<img src="http://www.world66.com/myworld66/visitedStates/statemap?visited=AZCACOCTDEGAKYMEMDMANVNHNJNMNYNCORPARITNVTWV"><br/> <a href="http://www.world66.com/myworld66">create your own personalized map of the USA</a>
It's a pretty cool little app! I would love to get out on some more trips this fall but it probably is not going to happen until next spring!
