Apparently those dang packers win yet another award.  Lambeau were voted as the toughest venue to play in by the ESPN Staff writers:

And soldier field was ranked 5.

our very Own Metrodome (you know the one that's currently deflated) ranked 8, one of only 2 indoor venues to make the top ten.  Apparently the ESPN staff writers took bad weather into much higher consideration than not being able to hear in a thunderous dome environment.  But anyways here is the list, or you can click on the link to read the justification the staff writers had in voting the way they did.

1. Lambeau Field (Packers)
2. Heinz Field (Steelers)
3. Qwest Field (Seahawks)
4. Arrowhead Stadium (Chiefs)
5. Soldier Field (Bears)
6. Superdome (Saints)
7. Gillette Stadium (Patriots)
8. Metrodome (Vikings)
9. Lincoln Financial Field (Eagles)
10. Oakland Coliseum (Raiders)
