Michael,
I have had this idea, for a few years now, that I would contact clubs in Ireland in advance, tell them I was interested in golf course architecture, that I was travelling on my own and would love to be able to come to their club and play with some members.
I have done the mandatory trip to Scotland with my buddies and it was great but thought that if I could get some games with members of clubs, this time in Ireland, that would be even better. Sounds like your friend Tom has a similar idea. I just think that having a game with members, having a sandwich and beer later on, would be a great experience and a fabulous way to see the great courses of Ireland. Of course, the same could be done in Scotland and England.
I really look forward to hearing what happens to Tom. I was not so bold as to think I could pack my bag from course to course.
