I sincerely hope there will be more observations of this and that a good ID will be made. From the wonderful vantage point of Tucson, AZ and with maps, this alignment appears to aim at the Trail-West Trail area, though there are a _lot_ of holes out there. Activity there would be nice. Thanks for the report. Scott Bryan In a message dated 5/17/2010 4:57:24 P.M.

From the vantage point I had, the activity was just to the left of the left edge of the service station. I have no idea depth-wise where the burst may have originated from with regard to "closer to the station" vs. "closer to the tree-line behind" -------------- next part -------------- An HTML attachment was scrubbed...
