GPS Waypoint Navigator Instructions -- Apple Iphone (IOS)

Scenario:

You have decided to hike T5005 Benson Ridge Trail in the Sacramento Ranger District.  You want to use your smart phone to follow the trail and record your hike..  During the hike you see a lovely meadow off to the side of the trail, and you leave T5005 to enjoy that meadow.  At the end of the hike, you decide to share the route for this lovely "extra hike" with friends.  You then email the gpx file for the hike you recorded to them, and they download to their smart phones and follow your route.

There are several skills here: (1) Downloading a gpx file from this website, (2)  Importing the gpx file to GPS Waypoint Navigator, (3) Following that route, (4) Recording the actual route that you hike, (5) Emailing your gpx file to your friends, and (6)  Downloading the gpx file from the email.

I am sorry to disappoint you, but I do not have an Iphone, and I cannot give you tested instructions.  Please do work out the procedures and email me at lnftg14@gmail.com, so that I can improve this page.
