Alpacas are the most aggravating animals on planet earth. They scream and kick and spit way worse than llamas, or at least the ones I have dealt with do. Yes llamas will spit occasionally, but rarely purposely at people. About 90% of the times I've been spit on it was when they were fighting over food and come on, spit washes. It's not that bad. Take it from someone that knows. Lol. But I rarely get spit on. It's been over a year since the last time I got spit on, maybe longer.
There is no sport like barrel racing. It requires more speed than a sprinter, more balance than a gymnast, more grace than a dancer, and a stronger team than football.
