I agree with Becky.  When you visit the S.F. Bay Area,
go see the UC Berkeley Botanical Garden.  They have
two small greenhouses with a variety of Nepenthes and other
CPs.  Beautiful gardens and landscapes to walk in.
Tropical greenhouses with jungle plants and orchids.
Even in winter, it's a nice place to spend a morning
visiting.  Other greenhouses with other stuff, too.
