Thanks for the quick reply and the information Alan. This appears to be something that will help on the trip. I am planning to head down to Texas the first week of April to see if I can catch the wild flowers in bloom, and then head slowly further south. No time constraints, I guess getting old has some benefits!
Hoping to give the MFD a work out, that way perhaps next winter won't be so boring with images to process on these long cold days.
Thanks again, Ray
