I agree with both Lin and Karissa. That increased VTs hurt trial numbers in the long run and that earning VTs at training sites where dogs are comfortable, is not the same as earning them in trials. One short example... my dog Kaiden's contacts are 100% where we train and he has perfect start line stays. Add in trial excitement...well... and that becomes a training issue. However, I do train often and try to improve these issues so we can be successful in a trial atmosphere. A Q in a VT on a course with contacts for me is pretty much a given, In a trial...well, maybe 70% success. There is a difference with trial stress vs. VT stress.
And, although I said I think VTs should not be done away with, I'm saddened that people don't see the value in trials as much as before because of VT access. I'm trying to keep interest/numbers up at trials in our area because I'm afraid over time, we will lose them. So, I think VTs should be limited for various reasons. They should remain for those that have no access to trials.
Amy-- those you mentioned are frequent issues we all face when we trial outdoors in parks. I've been to many outdoor trials.
Mostly in Colorado, Iowa, and Missouri. Some had army helicopters flying overhead often, the army guys shooting at their practice range nearby, kids playing ball nearby, traffic, sprinklers, one had a race going through not far from the rings, volleyball areas, BBQ wafting our way, of course weather changes. How about Bears roaming through the park at night. Yeah, that was interesting! I could list a million distractions. This is not limited to VT areas. I have been to probably 25 outdoor trials over the years. They all have new challenges especially when they are in public parks, and they never deter me. Only the inconvenience of weather and hauling twice as much stuff in my tiny car. But, I still attend them.
