I was in Edinburgh yesterday, the great whore of the east, on a training course learning all about GIS mapping systems. Or at least learning about a specific type of software which is a GIS mapping system. I'll be there again today, and tomorrow too.
The return rail fare to Edinburgh is £21.90 from my local station. I would have to catch the 0740hrs train to Glasgow Queen Street, then change onto the Edinburgh train to get to Waverley station in time to walk (10 minutes) to the course venue for 0930hrs, and finishing the course at 1730hrs I would not get home again, or to my local station anyway, until 1930hrs. Total travelling time, about 3 hours.
The journey is 55 miles each way and I could probably do it in a little over an hour on the bike, at a cost of about £10 for the return journey. Total travelling time, about two and a bit hours. Total cost, about half that of the rail journey.
Can't think why I don't use public transport more!
