The first event I ever got was Oak's letter in my Pokemon Platinum, so I could get Shaymin (idk if I still have that Shaymin because my Pokemon Platinum is from US and my DSi is from UK, so idk if I traded it into SS, but hopefully I did), because I only figured out how to get wi-fi late the year before last. I've never been able to go to a non wi-fi event because they only happen in one place in Scotland, and my dad isn't going to drive me 20-30 minutes just so I can download a Pokemon. But yeah, since Oak's letter the only wifi events I've missed are Yellow Forest and Mew, because I never had Soul Silver when the Yellow Forest was going on, and I lost my Soul Silver during September last year. But yeah, I got 2/3 of the dogs anyway and I'm getting the last one on Monday <('-'<)
