Brian - of course you are correct - I keep mis-stating, remembering the activation must be within 80 vertical feet of the summit defined as the activation zone. Must be some obscure form of dyslexia 
Don and Gene - another tip - familiarize yourself with the SOTA rules for each region you activate in. Each Region has an Association Reference Manual (ARM) - Final Ascent and Activation Zone specifics are defined. W6 and W7N are local for us - as Brian states the last 100 vertical feet must be on foot - the activation zone dips from the summut to 80 feet below. So if you can’t make it to the summit you must be on foot for at least 100 vertical feet before you set up within the activation zone.
Gene - land line sounds great - send me an email with your number (email listed QRZ)
