Running an exit node from your workplace is also almost certainly a
bad idea, which leaves running it via neighbors' (the ones who let
their dogs run loose and play loud music late at night) wireless routers.
Then you can hope that when the police show up they will be distracted
by the presence of illicit substances and fail to consider who had access
the wireless network.

Hiding in a crowd:
At one time, secret messages were sent using newspaper
classified ads -- the internet is full of places to broadcast messages that
have special meaning to the intended recipient without raising flags.
Typically such messages would be very small and would direct the
recipient to the location of a larger message/file.
PRISM is said to work less by analyzing contents and more from the
web of connections. Since connections can be classified by protocol,
using https with sites other than your bank might attract extra attention.
Participation in a large array of public lists and forums by a "known
terrorist" could make it difficult to identify important contacts among
all the individuals who use same lists and forums.
