We live in the western half of the U.S. where shows are few and far between. We regularly drive 210 miles to the Utah shows (about 3 hours each way). We also travel to Boise a few times a year. That's about a 4 hour drive each way, but the October shows are a blast and are definitely worth the drive.
Our longest trip was to Carson City with 10 hours each way of dry, desolate northern Nevada scenery . . . . I don't ever want to do that again.
I would be reticent to trial at an indoor facility without good ventilation. We do frequently trial outdoors in both agility and obedience. We're planning to do so in August, September, and October. We're just careful to bring along our own shade and plenty of water.
