Congratulations, Peter. My son and I met you at Dayton Hamvention quite a few years ago. As I recall, we talked about DX pursuits, including 5B-WAZ, at that time.
As someone who has been stuck at 196 for years, I appreciate the difficulty of this achievement. I've compared it to walking on water. When someone in our local DX club gets their 200 zones, I make it a point to take them out to lunch. The last guy was KQ0B (now SK), who was featured in a CQ magazine article-- his last zone was z-2 on ten meters.
I also recall being on FT-8 one late afternoon on 80 meters and watched as WO7R worked z-21 for his 200th.
So, Pete, break out that cigar and scotch and bask in your accomplishment!
