Bandit (maurice) lives on Arran. I think he was registered on here. Drop him a pm. I have cross crossed and looped round it twice and stopped for a few nights once. Not many roads but what are there were quite good especially the crests around the north west coast road where I got some very big air.
I have been to Lewis twice. Not much of a spectacular place. The headland at the far north end was good, the black house museum was ok and a few of the beaches were worth a look but otherwise flat, windy and featureless. The best bit is that it is. joined onto Harris. Now that bit of the island is well worth a tour round.
