short answer = yes
but in reality scottish green fees for the big courses are about on a par with irish ones, the only difference being that ireland is ahead in the corporate golf market and has a few courses set up (k club, old head) at a ridiculous price...
...the one cost that differs by about 1000% between scotland and ireland is membership fees.... scotland rules the world in this respect, they are so cheap.... whereas now i live in ireland, i can't even join a semi-decent club for under $25,000... my hair is regularly torn out
