Here's a poetry contest for a good cause. It has a pretty steep entry fee ($20 for 1-3 poems) but according to the guidelines the fee is tax deductible. The Bridge Poetry Contest is open to poems on the theme of homelessness or humanitarianism. The contest is a fundraiser for the Metro Dallas Homeless Alliance. Entries must be postmarked by May 1st.
If you check out DailyHaiku every day (and you should), you'll see my name up there during the spring and summer. I just found out this weekend that I'll be part of the upcoming contributor team, which if you read the list is quite a group. (Yes, I'm the only one without a picture because I was late.)
