X re: PDAC You can do either but it is much easier to register online at no cost. Once you have done that you show up and you will be given a hand out. Goodie bag with maps of the boothes and so on. Just google PDAC and your in. Every investor in mining stocks should go to a least one of these. The best way to describe it would be like the first time you walked into Skydome. It's a bit overwhelming. I guantee you will be amazed.
PS leave your vehicle at home. Cheers
