I'm pretty certain the 25 year age difference between us would hinder that idea just a bit. Then there's that teeny tiny distance thing that's in between us too ! Oh and I checked the minepedia site and yes skeleton riders can climb walls with their spider mounts.
Piffle. 25 years isn't much of a gap. You get used to having different frames of reference after the first year or so. The distance would be more of a problem.
