Dude, you HAVE to. So many good Pokemans there. I've probably caught 12 or 15 with little to no effort. The Safari Zone in this game is much more forgiving than in previous games. I beat Claire at lunch, and she's being a whiny b*tch, all like "you won, but I'm not giving you the badge, screw you!" Off to the dragon cave, where I intend to find a Dratini.
Funny story: Waltzed into the dragon cave, first trainer I see whips out a Dragonair. First dude in my party is Gyarados. I am faster. I used Ice Fang--takes down half his health. Dragonair uses Thunder. Gets a super-effective critical hit. DEAD in ONE HIT. Screw you, Dragonair. Luckily, Feralgatr effed his sh*t up.
