So one thing that occured to me is that the way to the start of the Southern 100 isn't exactly obvious from the 08 runway, especially if you're doing it in the dark.
So, it's sort of a matter of either finding the Railroad tiles or the A5 roadway tiles, in the dark, with your lights.
So first off you
need to have the terrasync scenery, for the IoM not the simpler 2.12 scenery. A good visual check is to overfly the island in dayight in the UFO. It should be criss-crossed with dozens of roads. Also the Ireland scenery material is shared on IoM and the forests are really thick
Both race courses can be found if you depart the threshold end of Runway 08 onto the taxiway and explore the NorthWest Edge of EGNS's airport tile. There's berms along that edge, and topping the berms are the A5 and about an eighth to quarter mile further NorthWest is the Railway. Either one will take you directly to the start point of the corner of the A5 and the A3 in Castletown. Also with Rembrandt, the two lighthouses off the SW corner of the Isle of Man light up the sky somewhat in the direction you need to head to get to the start. Watch out for the Silverburn River, it's easy to mistake for a road in the dark. ( splash.)
The Southern 100 should be clearly marked out with Marc's custom road tiles and houses , trees, etc. If you loaded his scenery correctly..
Heading to Douglas from Castletown is a bit of a challenge once you finish the Southern 100 course.
You just need to follow the A5 back along the edge of the airport and it will eventually take a somewhat variable N~NE heading. You also luck out here because the lighthouse at Douglas also lights up the night Rembrandt sky rather luridly. Follow the A5 till it connects with the SW end of the Quarter Bridge, where Peel Road joins the A5. There should be a big old building there that I've put a couple of Fairy Flame-lights on to mark your way. If you pass the Braddon Church with it's spectral glow and fairy lights, on the left, after crossing the bridge over the River Dhoo, you're on the correct path.
Keep going down the road, it is marked with signs and red and yellow tire abutments at street corners. If you've travelled more than a few miles and haven't seen any custom houses or road surfaces, you're quite probably lost. But hey, it's only a small island and it's Halloween. Dig that chill running running down your back and embrace the fear. Let's go explore the lesser known parts of the Isle of Man, did you know there's two old WWII RAF airports that are now out of use? Can you find them?
Stop in Ramsey at The Swan and have a drink, and get your wits together. You're going to have to face 'the mountain' before it's all over..
Oh yeah watch out for the right hand corner at Creg ny Baa.
