Hey Guys
I am heading to honolulu and Helo (big island for a volcano walk) this week, then continuing on to San Francisco and Las vegas. (in addition to Yosemite).
I am sure there are members in this forum that might have travelled here. I hope you could help me find any hidden gems or experiences in these locations photographically or otherwise that I might missout on.

I am also looking for a good camera shop that is reasonable priced for tripods and lens (canon) in one of these locations.

and input is welcome.
