I have looked into naked eye astronomy but with all the light pollution, I am limited to solar and lunar observations and maybe a couple of very bright stars and planets. I currently do some bird watching and have been getting a kick out of Humming bird behavior, but Winter is coming and my subjects will be leaving soon. I also want more than whats available in those kits in hobby stores and sites. I have been poking around the amateur science sites like SAS and have not had much success — most things are equipment intensive. I talked to some mineral hunters and they are huge on travel and some of their activities I'm not fond of (trespassing on construction sites and risking arrest). So far, my best idea is Botany — thanks to the huge gardening culture, there's plenty of information and tools available for free or dirt cheap.
Any other suggestions?"
