Glad to hear your two friends are "going over the wall".......It's a great time.Everyone wins,the bars wont try to chrge you $4 bucks per Red Stripe,they make business,you get a good deal. The driver and Rob get respect for what they do.......Im surprised they dont charge.Im sure others have noticed the popularity and soon there will be a bus that charges....In the meantime have fun and tip the driver.....(dont eat the cake).
