Should I spit?

Two days ago, I took part in the Cochrane Reserve 2007 Christmas Bird Count. This is north-west of the city. We also stop and visit various farms/ranches in the area and talk with the owners about what species of birds they see on their land. Lots of very friendly, helpful people! This and another Llama live on one of the farms. Did you know that they have a bad habit of spitting? There are too many Llamas in Alberta now and people find that they are unable to sell them. They are useful, though, in helping to keep Coyotes away from the farm animals.
