I have a graduting senior that is looking for high-level playing opportunities this summer to better prepare himself for ACHA D-I next season.

I recall seeing mention of a summer league (Jr/College) 'round these parts last year. Does anyone know of a reputable (and worthy) league?

Player is located in central-PA and is prepared to drive assuming the level of play is worth it

Sounds like this is what you are looking for. It pretty much describes itself. http://www.hatfieldice.com/pdfs/CollegeEliteLeague.pdf
