Hi Trev
We usually all get there for around 08:00hrs, or there abouts, this is due to the high amount of ques on the day to get into the grounds, which is pants at times I do have to admit!! Not alot you can do about it though as such a big show
As for convoys I'm not too sure from up that direction huni however we all usually meet at South Mimms services around 6am!! But I think that means you'd have to come back on yourself???
