Ker-bump
Another dad in the playground was speaking to me about this.
I think the idea of Ocean Terminal has to be ruled out as the Russell Road Tram Bridge building means we would all have to cross the Corstorphine road to get onto the railway path.
As the other dad also said it might be a big slog to cycle home as it is all uphill (albeit a gentle slope) and there will be a number of kiddies on their own bikes (I think I will stick to the tow-bike again for this very reason)
So I think the canal to Ratho is the best plan for a starter ride, coffee and a climb, picnic optional. There are a few picnic tables at the clibming centre or better there are a load of them at and in the vicinity of the Ratho bridge inn for those that don't want to go to EICA. Again the EICA will be time dependent. We could stop at the big park (Murrayburn?) and use their outdoor gym equipment as they were on the list of possible improvements to Harrison.
Play it by ear, take it as it comes, wait for a sunny day and shout out via here and facebook (PoP group?) that we plan on heading with a few hours notice...
