No Worries JoJo,
As much as I enjoy a beer or two and some interaction with the chicky babes, waking up with a hangover with little sleep or no sleep and then riding even 20kms ain't fun, trust me, I used to ride professionally and it hurts big time, and throwing up on route isn't a good look.
You'll have a blast on the trip, I always have, not sure of percentages but don't think you'll be disappointed. Theres always the locals too
Obviously the organisers have to police the event well, and (at all the others I have been on there's been at least 2 police officers, usually riding) as there is often school kids attending they are rightly concerned at alcohol abuse.
So hope no offence was taken mate, see you there, oh and mine is a Corona
