I run a parenting blog, and I recently posted about excursion ideas for stay-at-home moms. Check it out here: http://mybossisteething.com/2010/08/excursion-ideas/
Also, look into MOMS Clubs. There are chapters all over the country, so chances are, you have one near you. There are probably lots of local moms groups, too. You might try going to your public library and ask about storytime sessions for babies. You can meet other moms that way, too.
