I've been told the snipped URL I posted, > http://snipurl.com/1w4c5 doesn't work. Can't explain that problem, but do have a solution, the full link: http://www.nols.edu/resources/research/pdfs/lightningsafetyguideline.pdf This should take you to a pdf file on the NOLS site. Enjoy, and keep your head down, move fast. -- Jeffrey "57" Zimmerman Sonoma County The Left Coast
