Hi fn, you can have lane four! Sure, the guide dog is more then welcome...but, he will have to start, in your lane, behind you! So, technically, you'll be, "following ahead of him" ("Catch 22") which will reverse as soon as the starting gun goes off to end the race and we all go back, (all the while staying in our lanes, as much as possible) to get more beer...
!!! You might just be able to pull off a win both ways... I'll check the rules on that..
.. Best to you, til....lat'r...GT...
