How does a player go about joining any of the leagues? If there are no teams around said player are his chances of playing in the league diminished? For the 16U and 18U is the hockey comparable to midget aaa in the T1EHL or is it better, or maybe worse? Is it a good route to take if a player wants to play college hockey in division 1? Don't mean to hammer these questions, I'm just interested.
Assess where you think you belong, and start getting in touch with teams. A lot of teams will be scouting showcases around the country (although more near their area) and holding open tryouts. This stuff is happening now, so if this question is for you personally and you're looking to play next year you should get a jump on it. Go on the USPHL website, check out some teams and see what information they have about joining on their site. If this is for you and you want some more personalized help, feel free to get in touch with me. I work directly with a few USPHL teams and know a handful of coaches/GMs personally and could probably help steer you in the right direction.
In terms of where you're from compared to where the teams are, I wouldn't worry about it so much. The Junior Bruins (Junior National Champions) had players from Las Vegas, Ohio, California, and some other non-traditional hockey markets. The Jersey Hitmen (ranked #1 in the country on myhockeyrankings power rankings) have players from Michigan, Ontario, Nebraska, Oklahoma, Texas, Illinois...list goes on. It's all about putting yourself out there for these teams to see you, and if you're the right fit they'll want you.
I would say their 16U and 18U hockey is at a higher level than what you're seeing from the T1EHL right now. Plus you're already in an organization that will likely have a team (or affiliate) in the higher USPHL divisions, so it's a good way to get yourself in.

That's a link to all the players in the USPHL who are committed to colleges as of today. Plus, assume that there are a few players here and there who have been shown interest but haven't committed yet (good example is Cloonan of the Junior Bruins, extremely talented player who de-committed from a DI school recently to find something better). In terms of Tier III junior hockey, you can't beat the USPHL Premier, and I think the Elite is on par with just about any other league in this country. Plus, if you're playing in the Northeast you have tons of colleges nearby with DI hockey programs and they are REGULARLY scouting the USPHL.
Not to delve into private conversations, but scouts and officials from higher level leagues in the US and Canada have seen the USPHL and are extremely impressed by what their Premier teams are doing. And if you want to see how high the talent level is in Elite, check out what the Springfield Pics did at Nationals this year. Being in the top 4 is not too shabby.
Again, if this is just an inquiry I hope this helps. If this is something you're looking at as a player, don't hesitate to send me a PM and I could probably help you out in more specific ways than I'd want to post on a message board.
