Opening weekend attendance numbers

This was an interesting read.
On Monday,  Casey Vock of Inside Lacrosse wrote about the National Lacrosse League's opening weekend attendance numbers.

It's nice to see the average up a bit, but let's hope the momentum from a great first weekend of action will result in some strong numbers for the league.

In looking at the first weekend’s numbers, the five arenas averaged 10,873 fans. That could bode well for the league, especially after the first five games of 2010 yielded an average attendance of just 7,480. The league’s attendance obviously receives a huge boost whenever Colorado plays at home, one of the highest-drawing franchises to play at the Pepsi Center in any sport, as well as some of the other staples, like Toronto and Buffalo.
Here’s a look at Saturday night’s numbers and how those numbers compare to each venue’s home opener in 2010, with Colorado and Calgary seeing increases and Philly and Minnesota dropping:

Game	Venue	Opening Night Attendance 2011	Opening Night Attendance 2010
Edmonton 7 @ Toronto 13	Air Canada Center	11,564	11,502 (01/15/10, 8-7 OT win over Boston)
Boston 10 @ Philly 6	Wells Fargo Center	7,940	9,330 (01/16/10, 13-8 win over Boston)
Rochester 11 @ Minnesota 10 (OT)	Xcel Energy Center	8,242	11,758 (01/15/10, 12-10 win over Calgary)
Washington 11 @ Colorado 10 (OT)	Pepsi Center	17,029	15,178 (01/16/10, 14-13 OT loss to Edmonton)
Buffalo 9 @ Calgary 10	Scotiabank Saddledome	9,590	8,112 (01/10/10, 12-7 win over Minnesota)
