I think someone should buy a matching pair of white track pants with plenty of room for lots more people to sign.
Then someone should volunteer to run the Auckland Marathon in it!
Having started the whole Tshirt thing I'd quite like to see it photographed at various sites around NZ, whether it be The Sky Tower, or outside the local Dairy, Whale Watching in the South Island or having a cappuccino in Wellington..... everyday or extraordinary just keep the photos coming!
Cheers
