I'm using the (free) GlideTrack iOS app. There's a similar android app. I'd like to encourage others to do the same.
That's a link to the embedded SSA tracking page for 9/23 @ Region 4 South. If that page doesn't work for you, let's compare notes.
If it does work for you, feel free to compliment me on my off airport field selection and textbook pattern :-).
