Sorry to hear about your club closing. Your question is very difficult to answer, but it would be a little easier if you tell us what you are looking for. Perhaps tell us what 'style' your old dojo was teaching.
Basically you can choose between aikido styles that choose to incorporate other MA's and new ideas or styles that try to develop aikido within its own frame.
By chance I started out in a 'original' Aikido style which has proven to suit me fine, but other people prefer to practice Aikido that contains elements from Karate, Judo, Jui Juitsu etc. I can't say what is good for you, but I am very happy to be a student of Shojii Nishio Sensei who as far as I know teach in the States on a regular basis. He teaches Aikikai aikido (One of the main 'styles') but with his own 'twist' since he is emphazising the importance of the sword and the jo in Aikido.
However - the most important thing for you to look for is a dojo that provide the attitude towards aikido and humans that fits you. Just as Nick says: go try them all and choose the place that makes you feel best. After all you are hopefully going to spend a lot of time there.
Oh by the way - I wish I had started at your age, so keep it up
