Communication with Dave was excellent and with quick and accommodating response.
We were heading for a girls trip and had arrived in the dark. We had missed the instructions to unlock the gate and went the other way and reached the top of a very steep hill, not knowing what is ahead of us in the dark. Called up Dave and he guided us immediately.
Next day we realised that we could have gone that way too but it was too scary when you are blind with no street lights and total darkness.
