[meteorite-list] Fireballs From The Sky: Bombarded

[Meteorites USA]

Over the past few months or so I've been tracking many fireball 
sightings and suspected new falls all over the world. Recently we've had 
no fewer than 4 right here in the United States. Not to mention the 
Denmark fall, Tamdaught, West, Westchester, Augusta, Sacramento, and the 
Merced Fireball. And the largest meteorite fall in Canadian history 
Buzzard Coulee! I'm sure I'm forgetting some.

Now another big event near MD, VA area:

<http://www.wtop.com/?nid=600&sid=1636442>

I asked this a week or so ago, but got very little response other than 
"yeah sure".

Isn't this abnormally high meteor activity? Is our planet traveling 
through a large field of asteroidal space debris right now? How can some 
many fireballs and meteorite falls happen in such a short period of time 
unless this were the case?
