Simply join regional, state, and/or national trade associations. (What groups are there near you? Check with the turf department of your state land grant university.) Within a short time you will be on industry mailing lists and receive info direct to you about pertinent national, state and local events. To try to list in one place all the events going on all over the country would be a major effort for someone to do, and then not too many would wade through this massive list to find something near them. If someone is on this forum, he/she must know a little about the internet, and how to search for items of interest to them. Or just spend a few days wading thorough Doug Karcher's <a href="http://comp.uark.edu/~karcher/turflinks/">Turflinks</a> (Need to use MSIE, Netscape won't access site).
