If you do do North Wales before hand. 
You will require the following before arriving at Morton on Friday afternoon. 
  
Snow Foam 
Megs Wash 
and a good Wax,because you would not want to arrive 'mucky' now would you.  
  
And if you are using the A5 to get to the Morton,after doing the Evo T.  
I know where this can be arranged, with a fine cup of tea as well. 
(If using the A55 to get there,you'll have to get Pete 'JetSet' to sort you out)
