Big mistake!
What was I thinking when I suggested that we map the coastal path from Teignmouth to Dawlish? Next time I get enthusiastic, I'll wait until the holiday season ends and the weather is a little less warm. Thank goodness for public transport - we didn't have to make the return journey on foot!!
It was a job well done though. We used the latest OSM map downloaded to the PDA plus, being able to overlay the track onto the map and have it 'track' with us, we were able to clarify a few anomolies and include a tunnel for the railway line.
