cactus nerd 

Any person with an obsessive interest in the study, collection, propagation and/or taxonomy of cacti and succulents, and possessing the ability to discuss and/or argue, ad nauseum, the finer points of each and every plant, while citing the latest peer-reviewed research.

Only a cactus nerd would travel 500 miles to look at that spiny stick.
