Coming across a curious sight, joggers and pedestrians came to a full stop on the Wallkill Valley Rail Trail on Saturday. What they saw was this: A half-dozen humans leading a quarter-dozen miniature donkeys down the trail. But that was all a part of Steve Stiert’s plan. Those tiny donkeys -- roughly as big as large dog -- are a part of the community service project “Little Brays of Sunshine.” Stiert and his fellow donkey handlers were using their walk on the rail trail to socialize the animals to random encounters with unexpected humans.
