I have been looking for a Killarney track for so long, and was so excited to find this post. Well done! I will pay money for a good rendition of this track. In fact, I have actually been at a point where I was trying to find people to create this track for me, for payment.
Can you please get in contact with me. I will happily test out your track, provide feedback and also perhaps connect you with people who can help you build, if you are interested. And if would be happy to contribute some money towards your project, if it will help you to work faster on this. 😉
Please reply here, but also email me at bertuseng@gmail.com. Looking forward driving your track.
