Transport logistics are challenging for some of the 32 counting areas for the independence referendum, and how soon the votes can be delivered to the national counting center will depend on geography and weather. Some of the counting areas are urban centers with good transport links, but others are remote and reachable only by boat or by air – Comhairle nan Eilean Siar, the Western Isles council, plans to use a helicopter to deliver its ballot boxes. An Electoral Management Board for Scotland document:
[…] Whatever logistical and transport plans and contingencies are put in place, weather or road conditions may delay the receipt of ballot boxes at a count. This would delay that count and, as a consequence, the overall national result.
