I finally figured out why there is so much glass compared to the UK and thats because they sell pretty much all their beer in bottles where as the UK sells most of its beer, or at least half in cans.

Glass works its way in and I'm checking tires every week and usually cut out about 5 bits.

Hope you win the war Fairmont. Its such as shame graffiti and litter. NZ is such a beautiful place yet the youngsters don't appreciate it.
