• Mommy Poppins has posted her 2009 Halloween Guide for New York City kids, with the best haunted houses, parades, free events, and more. Tribeca makes the cut of top places to trick-or-treat: “The stores decorate to the hilt and throw open their doors to greet the kids. It’s a nice scene and who can resist Japanese treats from Nobu or homemade cookies as treats from Bouley?”

• Anyone wearing a costume on Halloween gets a free yoga class at New Field Yoga, a new studio at 27 Cliff Street (between John and Fulton). Dressing up as a yoga student does not presumably count. New Field Yoga also offers private tai chi and qi gong for $50 (by appointment). For more info, email info@newfieldyoga.com.

• I got an advance look at “Plastic, Rubber + Wood,” the inaugural group show at the McNeill Art Group Tribeca Project Space—which turns the lobby of the new Artisan Lofts building into a gallery—and the art is striking. Entrance is by appointment, except this Wednesday there’s an opening reception from 6 p.m. to 9 p.m. It’s a good idea to email mcneillartgroup@mac.com if you’d like to attend, because space may be limited (143 Reade).

• After leaving the McNeill Art press preview, I popped into Kiva Cafe for a coffee, and I met artist Eileen Hickey-Hulme, whose work currently adorns Kiva’s walls (in an exhibit titled “Explode!”). Piggybacking on McNeill’s opening, she’s having her own reception at the same time that same night. She’s a trip, to say the least: She uses fingernail polish and lipstick to make her paintings, and the invite postcard includes a photo of her holding two rifles against a fiery backdrop.

• Downtown Alliance is hosting Survival to Success, an event for local business owners, tomorrow from 8:30 a.m. to 11:30 a.m. (55 Broad Street, 3rd floor). You have to RSVP to attend. I’ll have a table there, so stop by and say hello!
