Got some vacation hours.

I'm considering visiting Crystallex headquarters and Toronto in general. Do they have a front office that you can visit, or is the office closed to the public? Do you need to set an appointment? Would this be a bad time, being winter? I'll be driving from Dayton, Ohio. Just want to make sure things are where they should be, and they are not running their operation in somebody's basement. Guess I should have done this before I invested my money...

What else is there to see/do there and along the way? Never cross the Canadian Border before, anything I need to look out for in the trip?

Any advice to making the trip eventful (in a good way) would be appreciated.

I'm also willing to take some pictures and ask some questions on the groups' bequest.

Thanks.
