Hey all,


I read a while back in a book about building docks
a method for making an anchor: pour about 100 lbs.
(or more?) of cement into a smallish tire. Sink a
U-shaped piece of metal into it to attach the chain.

Now, my question: is this an environmentally sound
anchor? Doesn't cement leach out or something under
water? And, wouldn't the tire decompose over time
under water? (I'm talking about fresh water in
upstate NY, by the way).

I'd think making some other disk-shapped mold would
be a better way to go, if one is using cement, just
wondering what anyone else thought.


Thanks,

Julien
