Go wild this weekend in Lawrence. We’ve got a few nature-themed suggestions for you here, including mouse races (yes, with actual mice), a day on the trails, crafting at the “Jungle” and “Breakfast and Birds” with Audubon of Kansas.

Mouse Races!

7 p.m. Friday, Theatre Lawrence, 4660 Bauer Farm Drive

“Guys and Dolls” opens next week at the community theater. To honor the occasion, Theatre Lawrence is paying tribute to the classic musical comedy about gamblers and con artists with “a night of betting, music and prizes” — and actual mouse races, because why not.

Bet $1 (i.e., donate to Theatre Lawrence) on your favorite mouse to win raffle prizes, or, for $20, name your own mouse. Theatre Lawrence has a few pun-y suggestions in this area, including “Rat-atouille” and the even more fitting “Secretari-Rat.” Call 843-7469 to claim your mouse, if it hasn’t already been taken.

The evening will also include a preview of “Guys and Dolls,” a cash bar and an activity called “Rat Roulette.” Not in a betting mood? The public can hang out and watch for free.

Celebrate Hidden Valley Trails Day

8 a.m. to 12:30 p.m. Saturday, Hidden Valley Camp, 3420 W. Bob Billings Parkway

In celebration of National Trails Day, Lawrence’s Hidden Valley Camp is offering free, guided hiking tours to the public from 11:30 a.m. to 12:30 p.m. They’re also asking guests to help with trail maintenance between 8 and 11:30 a.m. (You can do either or both on National Trails Day!)

Reservations aren’t required, but all volunteers and guests must sign in upon arrival. No unaccompanied minors, and no strollers or dogs, please. For more information, contact durandi@sunflower.com or visit www.friendshv.org.

Yarn fun at the Jungle

Noon to 3 p.m. Saturday, Lawrence Percolator, 913 Rhode Island St. (look for the yellow building in the alley behind the Lawrence Arts Center)

“Experience the Jungle installation and enhance it with your own yarn work” at Saturday’s all-ages crafting event, the first of the three to take place at the Percolator this month.

The “Jungle” in question is a large-scale textile piece created over three years by Catherine Reed, a retired chemistry teacher turned artist, according to the Percolator.

Crafters of all skill levels (and genders, the Percolator notes) are welcome at Saturday’s event, and the Percolator is supplying materials.

Breakfast and Birds

9 a.m. Sunday, Decade coffee shop, 920 Delaware St.

“Any or no experience” is welcome at the Audubon of Kansas’ first-ever Breakfast and Birds event, which pretty much entails what its name implies.

The fun starts at 9 a.m. in the Decade parking lot, where participants will carpool to the Prairie Park Nature Center for about an hour of birding before returning to Decade for “caffeine and conversation.”

Dress for hiking, and BYOB — that’s “bring your own binoculars,” naturally. Audubon of Kansas will provide the field guides. The event is geared toward those new to birding, but all kiddos must be accompanied by a parent or guardian, it should be noted.
