I think then your best bet is to go to as many shows as you can before then while you still have your vision. Do you need the name of a good Ophthalmologist?
My 2 cents see both Hamilton and OTTC. I don't know when you are coming but if in July you will be too late for Hamilton that show closes on May 3 (unless there is another extension. Note: Your post is very confusing and I am interpreting what you may be trying to say. So sorry in advance (not really) if your questions did not get answered!
