If we don't dream - it won't happen... well maybe
Anyway you could try contacting K9Pro and Agility Click who run seminars that people travel from interstate to attend about what they need in a venue and nearby accomodation. How many motels let dogs stay over? Even in crates?
I traveled to seminar in NSW Hunter Valley recently and the venue sucked. It was "dog friendly" in a completely no rules kind of way... people were not picking up after their dogs, there were aggressive dogs off lead, the cleaner's live in dog roamed the place fat and with a completely matted coat - very pathetic BC next to all the agility dogs there. And they picked up the rubbish for about 80 people - once a week instead of daily. And we were all cooking and eating there because there was nowhere else to go. The roads were not night travel friendly at all. They were barely day time travel friendly - one or half lane unsealed goat tracks - at least an hour or so to the nearest "towns" which did not have things like places to eat or get takeaway food.
