Very Cool !! Rock on. Drummer girls are the shi-ot! Thats Flam-tastic.
Drums and apartments are a horrible combination for sure! but dont feel bad for not getting an electric kit. like you said, they have a way different feel to them. Unless you start getting into the really high end electric kits like Roland TD-8 + , i find electric kits have wierd response time to them and have trouble with dynamics. I had a yamaha electric kit for years and years, and i would play my acoustic kit anyday of the week over the electric kit. Nebraska in't too far from where i am in Colorado. You should be getting some spring weather about now for your garage. I used to play in a band in rental space in phoenix in th middle of the summer, it was all enclosed, it would get like 110 degrees + in there, I feel ya.
Practicing is great, but the easiest way to get better is to find some fellow musicians, maybe on craigslist. You got the practice space already, and chick drummers are in high demand... Little secret, drummers outnumber guitarist and bass players like ten to one. Ive never had trouble finding a band. Even if you are still learning and the band kinda sucks, the hours that you spend practicing with the bandwill help tons!
Plus, band is a great social outlet for a possibly awkward Aspie kinda person. A band is a brotherhood/sisterhood. There no other feeling that quite compares to the connection that happens when you all collectively ride the same wave of music together . The same tempo and melody all working together as a unit. Its a beautiful thing.
One more thing, and im sorry to give you all this unsolicited advice, but one thing that newer drummers do that drives me nuts, is trying to play too many notes on the snare . Keep the 2 &4 solid and put the extra notes somewhere else ie.. the bass drum. DOnt believe me, turn on the radio to any random song and see if they are playing a busy snare... ok, thats really it, ha sorry! Not trying to be a know-it-all. that is good advice from a seasoned drummer that i wish i was given when i was younger. .No more advice, I promise.

Rock on duder!
