Last summer I noticed that there was a shit load of random small aircrafts and helicopters around west toronto.

I use to believe that the infrared could pick up plots in the brush but almost always its an aerial spotting of green vegetation surrounded by dead, brown plant matter...thats why using 'urea' (sp.) 46-50% N fertilizer helps:thumbsup:

it would be interesting to see what farmers have to say about 'avoiding l.e.o.' there should be a thread for it :jointsmile:
