Shame if you are over here and don't join us at Art in the Open. Its at the last weekend of July with a few paint-outs either side of that and is in Wexford, about 80 miles south of the capital. Our group (SEPA) paint out regularly and you are welcome along. There is also a Dublin group who paint out at least once a month together.
Have a look on Plein Eire (google it), a wee Irish version of this fantastic site, for details.
