My Goal This Summer After

My Goal This Summer
After reading all about my new hero, Robert Fulton, I've decided that I have a new sartorial goal this summer. To wit, I wish to:

1. Find and purchase a new, top-quality pith helmet.
2. Find a location/setting/event where I can wear the pith helmet. This event must be such that the pith helmet must not look out of place. In fact, I'd be really happy if I could find a place where I'd look funny if I weren't wearing the pith helmet.

Your suggestions are welcome. First of all, where does one find pith helmets? The East side somewhere, I bet. And where do potty expatriates hang out? Lepidoptery meetings? Gatherings of the Hash House Harriers?
