I have poison ivy vines about 1" thick climbing up all the hardwood trees in my front yard!..I chop them off at ground level and they die,then grow back every year....luckily I dont seem to get a rash from it much,only when I sharpen mower blades that cut it is when I notice any allergic reactions..but I am hesitant to burn any of the trees it is growing on if one should come down,and I am not likely to try pulling the vines off the trees either,as they are firmly entrenched into the bark,it litteraly grows into the tree practically..
Another thing I hate is thorn bushes,I dont know what they are,I dont see any roses but they look like them--maybe rasberry bushes or something similar??--anyway,those always grow next to the lawn and hang over it,so every time I ride by on my mower I get slashed by the thorns,and have gotten flat tires from the *** things too--I hack them down every year right to the roots,but they grow back bigger and stronger every year...
My yard has a ton of old cherry trees,the type with real shaggy bark and inedible fruit,and most of them are dying off,they drop big branches and threaten to crush my vehicles or bust the windows,and I'm slowly cutting down the worst ones after the tops come off them,most are 30-50 feet high and 6" or bigger around...they do throw nice heat for firewood,but cutting them kills saw chains and its tough as iron to split,very stringy--and more often than not the centers of thelogs have a billion carpenter ants in them,so any I burn I must split right before burning them,and have the dustpan and broom handy to sweep up the billion ants ,and hope I got them all,so they wont eat my back wall of the garage AGAIN like they did 10 years ago!..

...it stinks having these widow makers hanging over the house and garage,driveway,cant park anywhere without fearing your vehicle will get hit by a branch or the whole darn tree now that 30 years has passed since we built the house..
We had a bad windstorm the day the rest of MA got blasted with snow,and the healthiest looking sugar maple tree in my yard had a huge branch shear off right at the main trunk about 8" thick and 30+ feet long,it took my fence down and landed halfway in my neighbors yard...why that tree busted like that and none of the rotten cherry ones did not baffles me...now I'm worried the rest of the maple will snap off where the branch did,a good 20 feet up,if it does chances are good it'll come towards the house,the way it is leaning..there is another dead tree I dont know what kind,that is 60 feet high and a good foot in diameter right on the property line thats leaning over and isn't going to stay standing much longer too,at least that one will fall towards the street and not the house or garage --hopefully!..
I've been trying to clean up all the dead or downed trees ,but its a losing battle doing it alone..I also may not BE here for long,so I hate to kill myself doing all that work,then find out the place is going to be sold off too...so I'm just cutting the ones down I can handle that wont hit the house or just waiting for them to come down by themselves and picking up the peices!...
