I thought that I would compile s short list of the sites that I like. The first being http://www.mrsgreengoesmainstream.com Mrs. Green Goes Mainstream is a local radio show that focuses on green topics. Check out the site, it has all kinds of goodness.
My favorite printer in the whole wide world is http://www.wgiprint.com Wizard Graphics not only prints on recycled paper, but they print with low VOC vegetable based ink. They have great customer service and their printing is exceptional.
This really isn't a "green" site, but my absolute favorite travel site is http://chuckmanes.worldventures.biz/ It is my husband's travel site but they price match and you can rent condos, apartments in addition to hotels. You can also rent cars and find airfare, check it out if you are planning a trip.
I direct anyone who asks me questions about the cost of cloth diapers vs disposable diapers to the Diaper Pin's diaper calculator http://www.diaperpin.com/calculator/calculator.asp. The diaper calculator gives an unbiased look at the reality of diapering.
For some reason the hyperlinks wouldn't work for the last two sites, so I bolded them. Copy and paste the addresses into your browser.
Lastly, my friend Nonie is doing an amazing thing for the breastfeeding community, it's called Mom's Breastaurant. http://www.momsbreastaurant.org She goes around the country to different festivals, fairs and expos, and offers moms a safe, comfortable place to sit and nurse their babies. Nonie doesn't charge for this service, which is even more amazing. Check out the site and support her if you feel like she deserves it, I do.
