Route 4: Caught a Mankey, named it 2-Late. Bought a Magikarp in the Pokemans center and named it Rowe.
Route 3: This is where my modified rule comes back to bite me in the ass. Nidoran Males are the rare mons here, because of their 1% encounter rate. That's right, 1%. Mt. Moon isn't any better, as Clefairies are also a 1% encounter rate. I give up and forge ahead after my whole party -- Rukh, Absalom, Rowe, and 2-Late -- hit level 15.
Cerulean City: The Rival's Pidgeotto knocks out Rukh. Seriously, I have a Bug-type, a Fighting-type, and a Magikarp. Who else was supposed handle that bird? :(
Route 24: Abra, named Lucy. My current team is now a Mankey, a Butterfree, a Magikarp, and an Abra. If you'll excuse me I'm going to grrrrrrind until the deadweight half of my team evolves. Good thing, too, as Gyarados's Bite is all that got me through Misty's Starmie.
Route 5: Bellsprout, named Libertree.
Route 6: Meowth, named Penelope
Route 25: I'm such a :F I didn't even realize I entered a new route when I was on my way to Bill's house. So I run back here to nab a Pidgey, which are actually uncommon here. Also HOLY CRAP IT IS A DUDE I name him FriendZone.
Since Lucy is now covering Psychic-type attacks and Libertree can handle status effects, I swap Absalom out of the party in favor of taking FriendZone. And I grind everyone up, because Christ the S.S. Anne is always a slog.
Route 11: Drowzee was always my favorite Psychic-type back in the days of playing Blue on my old brick-style Game Boy. Since I didn't have anyone to trade with, I couldn't evolve Kadabra up, and having a fully-evolved mon seemed important. Anyway, I catch a Drowzee and name him Tapir, which is what I always called them back in the day.
Diglett's Cave: I catch a Diglett and name it Salsa.
I switch Salsa into the party instead of Penelope. Next stop, the S.S. Anne and CUT!
Current Party: Lucy, Kadabra. 2-Late, Mankey. Rowe, Gyarados. Libertree, Weepinbell. Salsa, Diglett. FriendZone, Pidgeotto.
In PC Storage: Absalom, Butterfree. Tapir, Drowzee. Penelope, Meowth.
RIP: Rattata, Benny. PikaCHUMP, Pikachu. Rukh, Spearow.
