<font color="blue"> what are some good uses for the chippings? </font>
We use them around the house where we have flower and shrub beds. They are great for controlling weeds - do the weeding (no easy way - this is by hand), then put down pre-emergent weed control (optional, but we've found this really helps), and then mulch the heck out of the beds with the chips. Looks pretty good, and when you do that weeds are controlled for a full growing season. If any do poke up they can't establish good roots in the mulch. Then the mulch turns into compost. Have to do this pretty much every year, but it really is worth it.
We also use it in our garden for pretty much the same thing. Can't really use the pre-emergent - we try to keep it organic, plus we do a fair amount of direct seed (and with the long growing season we're *supposed* to have we can often do multiple crops per year - but this year we can't plant anything in the muck).
And if you do composting, chipped wood is the perfect "brown" mixture to balance "greens" like kitchen scraps and lawn cuttings.
But if you're in the "barely can find my property because of all the junk growing on it" you are definately better off with burning. Just use your tractor to pile up the stuff and light it on fire. Don't worry - enough will come back that when you get the time you can always go the chipping route /forums/images/graemlins/laugh.gif.
