Your routefinder is taking you too far north, in my opinion, using M4 and M5 from London is too long, you'd be better off, doing M20, M25, M3, A303. Others may think otherwise.
Has anyone seen the Kelpies yet?
Anyone else at BSB Knockhill in June?
Or personally, I'm a sucker for anything involving Breakfasts or Fish & Chips, particularly on the coast.
