I don't travel to trial, I'm lucky and generally have a trial about once a month and thats enough for me. Are there multiple venues near you? You may be able to trial more if you compete in a few different venues like AKC, USDAA etc. I personally don't have the resources or desire to drive 3+ hours to compete, but I am sure others do.
