Splooge.... Everything about that picture is awesome, racks included.  Absolutely beautiful, S.Albert.
And AcidRock, yours looks pretty darn nice too.
Maybe I should build my own rack.....  I've never seriously considered it, but I have no doubt I could do it.. I've done more complicated stuff before anyway.
This summer I have a rather awesome wood working project ahead of me - some friends and I are building an enormous 12'X12' raft with a 16 foot mast housing a rather sweet looking sail (we stole the design off of an old sailing ship design we saw in a picture).
Should hold upwards of 5 people, and have room for a couple hammocks and a barbeque.  Going to be awesome!
Also we're gonna do some serious recording this summer, sweeeeet.
