Oh poo!!, I said as I steped on the soggy and wet grass. Me, my class and room 8 were at the the smally transfer station. We were there to lern about recycling and rubbish. The lady infont of us said stuff like what you can recycle and what you can't recycle.
The lady's name was Angela. My fave fact that Angela said was that our poler fleces were made out of plastic."in 10 to 12 years you could walk across the land fill, because it would be filled with rubbish," said Angela. As we walled past the land fill I smalt it it was bad in was cow poo. Wall it smalt like poo.
