You're going to have to pay to get up there and then for the fuel on the way back. Just make sure you've got plenty of ratchet straps and a ramp or something else to get the bike in. You could do it in a long day if you've got someone to go with you.
Quite looking forward to the ride home but your right it could be hard work.
Managed to get a great deal on a flight to Edinburgh which convinced me - £5.99 plus charges, a total of £25 and gets into Edinburgh at 8:15am so allowing an hour or so to get the bike sorted I have a good chance of getting home in daylight. Just need to make sure I wrap up well, think I need a new pair of winter gloves
