Hope my little tweaks are within the rules and spirit of the building competition? Please don't refrain from letting me know!
I doubt any of my local quarries will support one of these monsters (we don't mine uranium or diamonds in these parts) so I am off to surf the web in search of big, big loaders and get more inspired!
Finally, come on the rest of you! Pick that little free model that's been lying all alone and neglected on your hard drive and get building!
