I didn't get out on the wrong side of bed, you just seemed very pompous in your opinions.
I have only ridden London once on a Saturday, and I posted nothing about it, and it was only the local's from my area that went, and it was very good. I have ridden London on a Sunday a few times and It's been quiet aswell.
The reason the ride was organised on a Saturday was because many a person locally can't get Sundays off work, and hence wanting to go on Saturday.
I prefer Sundays, you don't get chucked off of places so much. i can go on Sunday, but most other people can't, hence the reason I am organising it for Saturday.
If you can't go on Saturday, don't even bother posting, simple really.
Sam.
