Exhibiting photos is a lot like having children. If you "wait 'till you can afford them," you'll probably never have kids; likewise, if you wait until "you have something worth exhibiting," you may never get around to exhibiting. Just set a date, make up your mind that you're going to exhibit, and GET TO WORK! With all the awesome subject matter in Ireland, the great workshops Fintan and Peter are organizing, and the loads of talent you guys have got going, an Irish APUG exhibition should be tops. And, you have good venues in which to do them!
Now stop with the excuses and get to work . . . .
