Well, heck! I missed the X / Y chromosome discussion.
That's quite some fence the golf course has; do they really think their members can hit that far into the woods?!
I have completely different tactics to suggest. First, develop a written record of your communications with the golf course. Call one more time and write down the name, title, and phone number of the person you speak with, the date and time of day, and your questions and the responses you receive. This is the backbone of your written record. Then...
Write a letter to the management/ownership of the golf course (ooh, is it a membership country club? lots of potential there for trouble-making) about the
potentially toxic wastes on
their property which are visible from
yours (include photos when you do) and the refusal of the staff to address your legitimate concerns. This next just occurred to me: maybe they
lease this property from someone? don't know how you would find out, but that kind of stuff piling up sure sounds like a violation of most leases I've ever heard of.
It might also be...ah...helpful to
send a copy of such correspondence to whichever county/state agency is in charge of toxic-waste reduction/environmental code enforcement/groundwater regulations (if it appears that toxic wastes are being tossed out). At the state level, this will be the
Alabama Department of Environmental Management. Phone or email around, after digging on the website, and find individual people's names. Copy the letter to them, showing full name and title/position. Keep a record of the phone numbers for yourself. Me personally, I'd show just the name and title/position on the cc's; if the golf course wants to call the government, they can find the phone numbers on their own sweet time, you know?
Email might do as a secondary method of communication in situations like this, but writing still packs a wallop, esp. when copied, including photographs, to...let me get my mental list out:
--newspaper reporters (yes, they still exist)
--TV and radio reporters (they can get good camera views from your property; radio can sometimes cover local news, depending on your own locale)
--local web-based folk (e.g., the Patch series of local newsletters)
--local city council representatives and, going up the food chain, county commissioners, state legislature reps
There
is a way; if absolutely none of these work, then the "make a gate and tackle the stuff yourself" approach may just have to be it. But I suggest that the golf course/club has the money, staff, and equipment to deal with it, so give them the...ah..."opportunity" to fix it first. It seems that you've tried nicely, in private. Well, so much for nice. *sigh* Folks just didn't get it, did they?

Some people's moms just didn't train 'em to clean up after themselves, it looks like.
Now it's time for Ms. Determined to take the stage. Best wishes.
