Top o’ the morning to you! (or afternoon, or evening) We hope you’re having a grand St. Patrick’s Day!

And while you’re at it, we can start thinking about another holiday celebration --Earth Day 2011.

In Columbus, the Green Columbus organization runs a great series of events in April. The first is a worksite weekend where volunteers can sign up and work at a community worksite (like a community garden, riverbank or some other outdoor site that would benefit from a little TLC). That takes place on Saturday, April 16, and Sunday, April 17.

The second big event is Earth Day itself on Saturday, April 23, where everyone gets together at the Scotts Miracle-Gro Community Garden campus on the grounds of the Franklin Park Conservatory.

But back to the worksite weekend. Registration just opened on March 15 for both volunteer signup and anyone who would like to get their community site registered as a place where people can volunteer to work.

Here are the details and links that you need:

1. VOLUNTEER at a community worksite and/or the celebration (FREE, and you get sweet perks) – Volunteer registration for Earth Day worksites scheduled for Saturday, April 16 and Sunday, April 17 will open March 15. Once you are registered, you may select the service project of your choice and sign up for one or more shifts. (Don't worry, we will never share or sell your info.) .

2. REGISTER A SERVICE PROJECT (Be a Worksite Host) – This too, is FREE with perks. If you have a "pet project" (like a community garden or a habitat to restore) or a "pet peeve" (like all that litter along your favorite road or river), register to be a worksite host and get 'er done. See Worksite Weekend FAQs here for details. Worksite registration is NOW OPEN. Use your 2010 login or create a new profile. Worksite registration closes April 5.
