If you're in the Twin Cities this weekend and want to keep Valentine's feeling going, check out Volunteer Expo, where 80 nonprofits will be on hand with opportunities.

"HandsOn Twin Cities kicks off its annual volunteer expo at the Mall of America this weekend, giving Minnesota do-gooders a crack at “speed volunteering” or a chance to explore longer-term volunteer work. More than 80 nonprofit groups will have information tables in the first-floor rotunda and four corners of the mall. Maps and directions are available in the rotunda. Name your cause and find a group making a difference. Affordable housing. Domestic abuse. Animal welfare. Senior issues. Mentoring youth. Environmental protection." -- Jean Hopfensperger, the Minneapolis Star-Tribune
