Have you tried using a GIST index on lat & long? These things are
meant for two-dimensional data, whereas btree doesn't handle
two-dimensional data that well. How many rows satisfy either of the
long / lat condition?
According to the analyze, less than 500 rows matched. I'll look into
GIST indexes, thanks for the feedback.

TIP 2: Don't 'kill -9' the postmaster
When I try to create a GIST index, I get the following error:
create index eventgeo_lat_idx on eventgeo using GIST (lat);
ERROR: data type double precision has no default operator class for
access method "gist"
HINT: You must specify an operator class for the index or define a
default operator class for the data type.
I'm not sure what a "default operator class" is, exactly..
