When I go to RCM it's the ONLY time I never tell my Mrs what time I expect to arrive back home
I have often left RCM's in the dark.
I arrived at their old place at 1.15am one night lol ......... bless 'em. Olly & Matt were still up as they knew I was on the way (my map sensor went at Silverstone).
I turned up with a mate and Olly had already sorted & paid for hotel, breakfast and P1 was ready at 10.30 the following morning.
