azelma, no one here knows what the heck they are talking about in terms of admissions methods. I doubt you need research ops or summer programs to express a love for an academic subject. Do you read about it in your free time? Do you have a huge desire to find out more? Show that you love the subject that you wanna major in (as your posts seem to indicate) and I'm sure that will show them that you care about the subject. The whole need to show a
"passion" is so ridiculous, frankly. I really seems like the next big fad in admissions (like community service or "well-roundedness" was ea few years back.) To me, planning your schedule to have a "passion" just so you can get into a great college defeats the purpose of having a passion in a subject. If you care a lot intellectually about your intended major and can show them that genuinely, then I am sure that will impress them more than some kid who prepackaged their schedule with internships and expensive summer programs just to build their resume.
You said you live in a rural community where research is not available. I am sure that they take that into account when they review apps. Not every student is a white collar city kid who has the time or opportunity to do groundbreaking research. That is what college is for: to explore your intellectual interests and be able to become a true scholar.
I have a strong intellectual interest in a rather unusual subject like you do and I am just hoping that shows through in my application. I don't feel the need to do an activity that I am not interested in just because it looks good. If college admissions officers have a problem with that, then the college is probably not the right place for me to be anyway. Just try to keep things in perspective, do what you love, and cross your fingers.
None of us have any idea how this goes, including myself, so let's all do what feels right inside and hope for the best.
