Saturday's Ride the Rim, a back roads mountain bike tour, at Glen Rose's Fossil Rim reminds us of a race we once took part in at Fossil Rim when we were young. It started like any other school field trip as we packed into a yellow school bus, but when our bus neared Fossil Rim's steep, downhill trail, the yellow dog's brakes went out. We held on for dear life as our bedraggled bus driver held the reins at more than 50 miles an hour, and somehow, we didn't careen over the edge. Sure, the memory is still fresh, but we figure biking the Rim to view cheetahs, black rhinos and wolves in the Intensive Management area of the park can't be half as scary. Registration is $30, which includes a T-shirt, snacks and a guide. The family ride is at 9 a.m.; the moonlight ride starts at 7:30 p.m. Call 254-897-2960. --Sam Machkovech
We cheer on squirrels teetering on telephone lines and root for rabbits huddled in roadside culverts. We become slightly annoyed with raccoons wrenching off trashcan lids and yet are amazed at their dexterity. Really, aren't we all just animals trying to make it in the urban jungle? Learn more about non-human city dwellers (and meet a critter or two) at In Celebration of Wildlife: Texas Varmint Lovers Tea Party. Specialists will be available to discuss the importance of wildlife to a healthy ecosystem, how to handle an injured or orphaned animal and other wildlife topics. Embrace rascally nature at Texas Discovery Gardens, 3601 Martin Luther King Jr. Blvd., on November 7 from 2 p.m. to 4 p.m. Cost is $3 for adults, $2 for seniors and $1.50 for children. Call 214-428-7476. --Michelle Martinez
We were never much on running. It's hard on the knees, hard on the joints. Man, it's just hard. Walking, however, we can do. We can walk for miles and miles--OK, three miles tops, but that's all that's necessary for the Alzheimer's Association Memory Walk 2004 Fundraiser on Saturday at 9 a.m. Three measly miles--man, we probably clock that just shopping at Target. And while there won't be any Isaac Mizrahi clothes to browse through, the event has an even better view. It winds through the Dallas Zoo, ending at the intriguingly titled Cat Green (kitties for the kiddies!). There will be clowns for the young'uns, as well as a children's play area. So dust off those sneakers and put on your game face. It's all for a good cause--no notes from your mom, OK? To register, go to www.alzdallas.org or call 214-540-2404. --Sarah Hepola
