Hi Bob,
I have done the same thing for locations of each STAR in Google Earth for all of the STARs that I have attended. I've attended every STAR since 1989 in Wakefield Michigan. I've looked at some of the locations on your map and have a couple more that you can update.
STAR '89 was at the Indianhead Mountain Big Snow Resort lodge just outside of Wakefield, MI, which is very nearly at the extreme western tip of the Upper Peninsula of Michigan. The rally site was a couple miles west of Wakefield, on the north side of US-2. The resort is still going today and can be seen in the satellite imagery. Here is a link to Google Maps showing the location

STAR '97 was at Lake Eufaula State Park at the resort. The resort is no longer there, but you can still see the parking lots in Google Maps. They show up as roads, and they are clearly visible when you zoom in in the Satellite imagery.
To find it, from the town of Eufaula, go up US-69 across the reservoir to Hwy 150, then go west until you come to a sharp right turn to the north. There you will find Megan Bell Blvd, which goes south from the turn, and becomes the parking lot for the lodge.
Someone else told me that the lodge actually closed about 2 weeks before STAR that year, but they reopened it for the week to honor the contract that had already been signed for STAR. It closed again after we left, and was demolished about 10 years later.
Here's a link to Google Maps where the lodge was located
