Whalan, Minn. – Between bites of Elvis Peanut Butter pie, Becky Talle explains why she's ventured here to bike the Root River Trail for the second time in three years.

"Just being in nature, the great outdoors — with no bugs," said the 34-year-old Eagle Lake kindergarten teacher, as she sits on the enclosed porch of the Aroma Pie Shop, just yards from the bike path.

While it's failed to transform every river hamlet into another Lanesboro — drawing flocks of tourists to their streets — the 60-mile Root River Trail is attracting visitors who otherwise might not be here. The Houston Nature Center, a crop of new B&Bs and Maggie Gergen's pie shop, which she opened here a decade ago, are among the destinations attracting out-of-towners.

Tourists are key to small towns without industry, said Matt Schutte, a Houston City Council member. "We're always looking for ways to improve the economy," said Schutte as he judged a soapbox-derby competition the last weekend in July at the annual Houston Hoedown festival.

A 2010 Minnesota Department of Natural Resources (DNR) report termed the trail "one of the key attracters of tourists to the area." The path generated about $2.3 million during the summer of 2009, according to the report.

Still, the controversial trail "hasn't been the economic savior people were dreaming about," said Dick Nethercut, a lawyer based in Harmony, who negotiated with area farmers during the 1980s to acquire land for the trail. "Expectations are always too high for something like that."

Becky Talle, 34, a kindergarten teacher from Eagle Lake, Minnesota, enjoyed a piece of pie at the Aroma Pie Shop — just yards from the Root River Trail, where she was cycling with friends.

But the trail, built on 49 miles of an abandoned rail bed in the 1980s and expanded in the 1990s, has had an impact.

The Root River Trail enabled the construction of the Houston Nature Center, said Karla Bloem, the center's director. And that provided the impetus for the creation of an annual International Festival of Owls, "which attracts the top owl people on the planet," Bloem said. "There's no other owl-festival weekend like it."

It remains difficult to identify with precision what local attractions spark tourist visits, said former state Sen. Duane Benson, a Republican farmer from Lanesboro, who had campaigned against the trail.

"The trail is part of it, but by no means is that the sole reason tourism thrives here," Benson said, ticking off tubing and canoeing on the Root River, tours of Amish country and Niagara Cave, south of Harmony, as other regional draws.

Dire predictions from when it was built of increased crime, litter and limited use haven't come to pass, though.

"We get the type of tourists that anyone would like to have," Benson said. "They don't even leave a gum wrapper behind."

Once they bike the trail, many of the path's visitors say they'll be back.

Elizabeth Vaught, 35, a Burnsville elementary school principal from Minneapolis, said she plans to return after cycling almost 100 miles on the route last weekend.

"It's really well maintained, with clear mile markers to let you know where you are," Vaught said, perched atop her bicycle outside the Houston Nature Center. "And there are tons of businesses along the trail that cater to bikers — outfitters, ice cream shops, pie shops."
