Navy Week and MacDill AirFest: Tampa will be overrun with Navy sailors this week. You can say hey to the hometown crew of the USS Florida starting at 11:15 a.m. today at a free outdoor ceremony and jam session with the Navy band Pride in Lykes Gaslight Park in Tampa. Check navyweek.org for a daily schedule of events. A fitting end to the week is the MacDill AirFest, starring the Navy's Blue Angels. Tens of thousands are expected to mob the base from 9 a.m. to 5 p.m. Saturday and Sunday. Admission is free and so is parking, as long as it lasts.
Ira Helfand at USF: The Student Chapter of Physicians for Social Responsibility Tampa Bay presents a free lecture at 7 p.m. today from Dr. Ira Helfand, who will speak on nuclear weapons policy and the health consequences of nuclear weapons, war and terrorism. Helfand, a co-founder and board member of the organization, was a member of the delegation in 1985 when PSR and its affiliate International Physicians for the Prevention of Nuclear War were honored with the Nobel Peace Prize. University of South Florida in Tampa, in the College of Medicine Building (MDA), Room 1096. (727) 403-1054.
St. Patrick's Day: It inconveniently falls on a Wednesday, so start thinking of excuses now. Some of the bigger parties are at Flanagan's Irish Pub in Dunedin, O'Keefe's Tavern in Clearwater and the Dubliner and Tank's Tap Room, both in Tampa — most with bagpipers, food and beer (green, if you must). Don't be alarmed when Garrison Channel in Channelside turns green. The Rough Riders will be at it with environmentally friendly dye 6-9 p.m.
Craig Ferguson: See the host of The Late Late Show at a totally reasonable hour. Ferguson brings his intimate and direct comedy to Ruth Eckerd Hall in Clearwater at 8 p.m. Wednesday. $29.50-$69.50. (727) 791-7400; rutheckerdhall.com.
Gasparilla International Film Festival: The fourth annual event hits various spots in Tampa from Thursday through Sunday with a few stars and lots of independently produced movies. And don't forget the parties, which are good places to spot celebs like Melora Hardin (TV's The Office) or talk show host Jerry Springer. See gasparillafilmfestival.com for tickets.
Chasco Fiesta: It kicks off Thursday for 11 days of family entertainment along the Pithlachascotee River in downtown New Port Richey. There's a daily carnival, a huge street parade at 1 p.m. Saturday, a traditional Native American festival and lots of live country music. Most of it is free. Visit chascofiesta.com.
