Erie advice

Hi all, A couple of buddies and I want to make the trek from wisconsin to see what ice fishing erie is all about. I've been reading all the posts and thank everyone for sharing all the good information. We will be bringing quads and have all the gear needed but due to a schedule conflict won't be able to make the journey until the 24th. Anyone care to share some thoughts or experiences on fish migration and numbers of fish caught as the season progresses?. Is it usually a first ice best bite kind of deal or does it stay pretty good through out?. Looking at the access spots, crane creek, camp perry and Catawba state park, do they generally all fill up with vehicles everyday and what do you guys do if they are full? I know, lot's of questions from a newbie, but any ideas or suggestions will be greatly appreciated.

Thank you
Kevino
