Most of you know my love of plein air painting and anything Irish (my wife is included in this category). I am a member of PLEIN EIRE, a superb site for outdoor painting in Ireland. Plein Eire is an organized group of artist from Ireland who are extremely talented and passionate about plein air painting. Check out their forum for some great discussions and view their lovely artwork.
