There are few graphics, so pages load relatively quickly. These folks aren't into stuffing non-Celtic stuff into a mold and calling it Gaelic or Celtic, either. If it ain't real, they'll tell you rather flatly. A must-see site for those of you who are into all things Gaelic. This site is devoted to exploration of the Bardic Arts.
Some pages are graphic heavy and slow to load, but worth the wait.
Again, lots of information packed into this one site, so bookmark it and come back often. You won't see it all in one visit. Several humorous pieces here, such as the Field Guide to NeoPaganism. There is a ton of great material here, including complete song books and other items that can easily be utilized by groups.
