I tried to talk my knucklehead D into a house reception and spend
the dough on bigger house, etc. No go...

V & I did a "destination wedding": we, (just us two), flew to big island of HI for 8 days, scuba,
sightseeing, drinking wine and got hooked, and mailed out the announcements from the fookin airport,
as we departed.

Tell your Mom & Sis to chill; it will be great, everyone will have a good
time, "they" will spend $30+Gs and no one will care a week later, other
than your Sis, her hub, and The'Rents,
