It sure cant hurt!
I think Gail Woolcott is a member under the NJLCA on lawnsite, hopefully she chimes in with some more info but I've been a member for some time now. The meetings as well as the tradeshow and speakers there have been very informative. Not only networking with other contractors but listening to and taking notes on what the speakers have to say has been super informative and a pretty good tool for my business. There are numerous member benefits as well and although I havent taken advantage of too many of them, they are pretty good. Check out their site I guess and see. Works for me and membership is very inexpensive
