Yes, the signal  go through trees, but you will need to calculate your
db losses correctly and take the trees into account.

You'll need to ask yourself these questions:
How many trees are there?
How dense are the trees?
etc.etc.

Check out this link:
http://www.qsl.net/n9zia/wireless/page09.html

That link above is awesome for wireless stuff.  It has loss calculators in
there and a bunch of other goodies.

Things that will effect your loss calculation:
1) Your antennas
2) Your antennas
3) Your antennas
(make my point yet?)
4) radios' transmit power
5) radios' receive sensitivity
6) distance between your antennas (known as free-space loss)
7) the "stuff" in-between your antennas
8) an amplifier, if you are using one
9) the cabling to the antenna
10) the connectors or splitters used from the radio to the cables or from
the cables to the antenna
11) anything I missed.  :)

If you do your loss calculation correctly, and you have a positive db left
over, you should be okay (dont forget about the fresnel zone as well).

Go with a couple of Lucent ORiNOCO AP-500s for the wireless if you want to
save some money.  Get the "gold" PCMCIA radio cards (RC4 encryption).  Ive
been playing with the Lucent ORiNOCO AP-1000 and it's way cool!

Ive been working on setting up a wireless-ISP, so Im becoming a "wireless"
junkie.  :)
