Ack...I've come across some of those before. They are annoying. I dunno what they are for though.

It wasn't just those on the road though, chunks of stone and even bricks were making a surface .. i'm pretty sure its to let vehicles pass without bogging down, but really the only vehicles that'll get down there are 4x4's .. sooo .. why bother hehehe mudplugging is fun! ... however there was a model aircraft field in the reserve so i would guess its to allow smaller vehicles to get down the track easily :) thanks for the comment *noselicks*

hmm maybe you have come across some ruins hehe. *licks your nose back*

*giggle meeps going crosseyed* ruins?! .. oooooh *puts on hat and boots and grabs shovels and other archeaolgy paraphanalia* woof!
