Anyone in and around Drumshanbo in Leitrim over the next few days should keep their eyes peeled for that most elusive of creatures - the Irish naturist.
They're not often seen but there will be a shot of them in Leitrim until Saturday as the 34th International Naturist Congress gets underway in the Lough Allen Hotel.
The Congress - which is being held in association with Fáilte Ireland - opens tomorrow with a press conference hosted by the Irish Naturist Association (INA) and the International Naturist Federation (INF-FNI).
While that will be open to the media, the rest of the three-day event will be private - allowing attendees to strip off - if they wish, there are no requirements - in the company of fellow naturists.
The Congress will finish up with a Gala dinner on Saturday evening - where presumably, the dress code will be quite relaxed.
Delegates from 30 international associations will be flying in from all over the world - including Canada, Brazil, South Africa and, of course, Europe.
Among the topics up for discussion is “Naturist Tourism” - an area many feel Ireland is missing out on as we don't have any designated naturist zones.
Pat Gallagher, president of the INA - which represents 300 Irish naturists - told the BBC that there is nothing sleazy about the naturist movement.
"We promote naturism as a legitimate lifestyle in Ireland, and try to have changes made in laws to enable people to enjoy the lifestyle," he said.
As Mick Ayers, the INF-FNI Vice President points out:
"Naturists are high spending, environmentally conscious tourists. The provision of officially approved naturist facilities would draw naturist tourists to Ireland. Even a small number of additional naturist tourists would have great benefits for Irish tourism”
And as an article in the Irish Times recently highlighted, it can be a lucrative tourism sector - it's worth €300 million to the French tourism industry with 3.5 million visiting their 397 naturist zones every year.
For people with no pants on, they sure seem to have deep pockets.
