I've gotten involved in the planning of two previous MB gatherings that never happened. Hopefully I'm not bad luck since I'm chiming in my .02
I used to live in MB, so if you guys have any questions, feel free to PM me. Depending on my monetary situation, I may just make it to the gathering.
Things you can do in March is still somewhat limited since a lot of places are seasonal and won't re-open until May. The good news is that last I checked, the Nascar place is still open during the off season, so we can get some killer go cart riding. The best strip club in MB is the Masters. Hands down model material ladies. Problem is, March is golf season and those rich bastards take all the strippers. If y'all want to do the strip club thing, we can discuss that later. I know of a few (allright, allright, all of them in MB)
If you really want hibachi food, Nakato's is the place in MB. They have better prices than Miyabi/Kyoto, better chefs and better food. I used to work there. Get some ideas about what you guys want to do and I can help. If you're bringing your ladies down with ya, we can kick them out at one of the outlet malls and they'll forget about where we're going or what we're doing.
