I definitely want to build some brown water stuff! Let me give you a suggestion, though: There's never a time when a group build isn't appropriate, but you might consider having this group build coincide with the 40th anniversary of a significant Swiftee event, like the establishment of the patrol unit, the point at which they changed their mission and started going upriver, or the beginning of Operation Market Time (in my ignorance, I may have just named the same event twice! The good news is this will generate more interest and there will be no political stuff (not that I've seen any political hassles on this board) but the downside is that you'd be doing the build in'06-'08.
In anay event, if you have the build I'll get in on it, but only if it's quite late in the year or early next.
