From the nurses who take your temperature at the local doctors’ office to the history teacher who has a full sleeve of tattoos under his button-up shirt, almost everyone has tattoos these days. This week, tattoo artists from 40 shops all over the country team up with body piercing specialists, circus acts and blues bands at the 22nd annual Tattoos & Blues convention. The three-day festival includes fire dancing ladies, tattoo seminars and contests for best ink. Tattoo newbies can get a glance at the tattooing process, and enthusiasts can get inked on the spot. Tattoos & Blues runs Friday—Sunday, Feb. 22—24, at the Flamingo Resort Hotel. 2777 Fourth St., Santa Rosa. Noon—10pm. $20—$35. 707.545.8530.
