SUMMIT COUNTY - Come springtime in Silverthorne, Lisa and Bart Myres are sure of two things: that they'll have plenty of chores around their house and that they'll also have plenty of moose around the house as well.

"We have had three in the yard at one time," Bart Myres said.

When the couple first moved to Summit County 40 years ago, moose were a rare sight.

"I remember when we went up in 73 to Wyoming and it was the biggest thrill of a lifetime to see a moose up there, because we didn't have them here," Lisa Myres said.

That has changed after three years of reintroduction. Moose are popping up all over Summit County neighborhoods.

"It's unbelievable we have them around our house in our yard trotting down the road," Lisa Myres said.

Lyle Sidener with the Colorado Parks and Wildlife Department says the moose population has been on the rise, with big gains in recent years.

"Since moose were reintroduced into Colorado in the 70s in North Park, they have expanded on their own into areas around Middle Park, Gramby, Kremmling and down into Summit County," Sidener said.

The larger numbers mean that people have a better chance of seeing them, but it also means they have a better chance of getting into trouble with an animal the experts warn can be dangerous.

The basic rule to avoid moose, if you're enjoying the outdoors with your dog, is to make sure it's on a leash so that it doesn't provoke the moose. If you see a moose, run away from it quickly.

"They really are unpredictable. They are a big animal and really don't have anything in Colorado to be afraid of," Sidener said. "There have been people injured by moose in Colorado."

That's some Lisa and Bart Myres learned a long time ago.

"You better stay away from them," Myres said.

For the Myres', moose are as much of a part of life in the high country as those spring chords.
