Riding Lesson??

You might have noticed that I haven't talked much about riding lessons lately. Mainly because I haven't had one in a while. My instructor (who I adore and would have to find a new barn if I can't ride with her anymore) has been having green-card issues (she is from Germany) so we haven't been able to fit anything in lately. Which really stinks! I am missing it a lot!! I don't know how long I should wait before I start looking for other places to go? At this point I haven't even heard from her in two weeks! How long would you wait? Finding a new instructor that I really like is always difficult, and she is going to be a really tough act to follow if it comes to that.
