Just to be clear, I was lead to believe it was Camden Fields again (which was marketed as Philadelphia previously), though cannot remember where from. The distance between the Northeast High School and the Fight is only a few miles closer and still different communities.
But as big a problem as the clash with the USARL is the complete lack of publicity for the Colonial Cup fixture that we cannot check anywhere to confirm. Philadelphia is just too vague. It is the 5th biggest city in the US, and the name can just as easily apply to suburbs as it does with Camden, NJ, which is much closer to downtown Philadelphia than any of the other stadiums mentioned.
How do they expect to attract anyone when no one can find out where they will be playing? Meanwhile in Canada they are already selling tickets to the final match of the series. Even if the AMNRL are scheduling it as a peeing contest they are still in the shadow of the USARL final with seemingly no publicity for the international match. The Canadians seem so much more professional in every way.
I know from Googling earlier on it was nigh on impossible to get any info on the actual location of the game. And you're spot on about the size of Philly. That North East High School is still about 15 or so miles from where the Fight play. I was quite surprised at the distances involved. What's really staggering about all this is that it's the AMNRL who are supposedly going to be behind the team we see at the World Cup.
But it is fantastic to see the progress the Canadians are making.
