bush walk

Bush walk along the track 
No slaking off said ranger rack 
In a flick of time  
In a blink of an eye  
I don’t want to tell you  
I just want to cry 
Huge green furry towers stood really high  
They were really scary  
2 years been living in fear  
When the dry season came  
What a shame  
The beautiful sky had turn to flame   
Gamba grass all black and brown  
Gamba grass was down to the ground  
Need to get rid of it  
Need to figure it out  
Researchers need you now  
Please help me figure it out
