1. Cypress Hill, the California-based Latino hip-hop group, promises to rattle the rafters in the Town Ballroom, 681 Main St., with its bass-heavy dub and reggae stylings tonight. For good measure, the group is joined by underground New York City rapper Action Bronson, who’s likened to Ghostface Killah and was a gourmet chef before he turned to rap. Doors open around 7. Music starts around 8. Tickets are $32.

2. A ceremony at 9:30 a.m. will mark the official opening of the state-of-the-art Dream Factory Technology and Robotics Laboratory at the Buffalo Academy of Science Charter School, 190 Franklin St. In addition to remarks by dignitaries, including Assemblyman Sean Ryan, there will be demonstrations by student robot builders. It’s open to the public.

3. Winter parking rules go into effect all over Western New York today, with most places banning all vehicles from sitting out on the streets overnight. An exception is the City of Buffalo, where seasonal restrictions on parking overnight on bus routes don’t begin until Nov. 15. The parking bans will stay in effect until April 1 unless we get another unusually mild winter.

4. The Post Office in Barker is among four in Niagara County that the U.S. Postal Service wants to cut back or close. Customers are being offered a choice of reduced hours, more roadside delivery, a branch relocated into a local business or consolidation with another post office. A public meeting on those options will be held at 6 p.m. in the Barker Central High School auditorium, 1628 Quaker Road. Further meetings are planned for Olcott next Wednesday and Model City on Nov. 27.

5. Christmas in the Country, the annual holiday crafts extravaganza, spreads its 400 artisans out over five buildings on the Hamburg Fairgrounds, where it opens today. Considered by some to be the best craft show in the nation, it runs from 10 a.m. to 9 p.m. today and Friday, 9 a.m. to 6 p.m. Saturday and 10 a.m. to 5 p.m. Sunday. Tickets are $8. Kids 12 and under are admitted free. Parking is free, too.

6. The Subversive Theatre production of “Radio Golf,” the final installment in playwright August Wilson’s 10-part Pittsburgh Cycle, opens this evening in the Manny Fried Playhouse in the old Pierce Arrow building at 255 Great Arrow Ave. in North Buffalo. Centered around a real estate developer’s campaign to become the first black mayor of Pittsburgh, it was nominated for a Tony Award as best play on Broadway in 2007. It runs through Nov. 17.

7. Rochester-based author Michael McCarthy will talk about the harsh realities of immigrant life in upstate New York in the middle of the 19th century and give selected readings from his latest historical novel, “Flight of the Wretched: A Journey to the New World,” at 7 p.m. when he visits the History Center, 215 Niagara St., Lockport. The program is free. For information, call 433-7433.
