There had been some mention of this on the UNO fan board, and it seemed far fetched at best. But, I've heard from another source that the Lancers are actively looking to move back into Omaha.
The talk on the UNO board mentioned Tranquility, which is where the Jr. Lancers play, and also where the USHL Lancers hold their tryout camp. They would need to completely re-do that place, but it could eventually work.
I had heard the Lancers have also talked with the Civic about moving there. I can't foresee the Knights being there after next season, so it could be a nice fit for the Lancers. The place has great hockey atmosphere.
Take it for what it's worth, but it seems this is gaining a little more steam as the days go on.
