500 feet on 63 yr old legs is not an easy task! I'd just sit there and swoon... 680 feet above sea level-- to 6400... or even 5800...nah... I'd be bent over pukin! Been there, done that on my 1st Westward Ho the wagon trip to live in MT on Mt. Capers, WY... Could NOT figure out how I came down with the "flu" being at a Conoco picnic!
Duh! Altitude sickness. Rather avoid that and I was in a lot better shape at 30 than 64!
It's amazing to me loving the outdoors, how you can shift geography a bit in this amazing country, and BOOM...you're up against things you have no clue how to handle... loose basalt/clay& sand,camo catcus, or when in MT, frost biting your lungs pushing a car in -25* in just 2" of snow!
You be careful out there and edumcate us tinhorns!
