Are you sure your not talking about 9/12 at ECC? Seneca army depot is this sunday 8/25. I signed up a month ago when my car was finished, but i am going to boston instead this weekend. If i was going this weekend, I would help you. A quick word of advice is if your like me (lazy,slow,night owl) get a good nights' sleep and make sure you get up early and at the event early. You need to be registered, car tech'd, and it doesnt hurt to walk the course a few times to familiarize yourself. I would also sign up for the novice class, this will allow you to have an instructor for the day, which is VERY helpful. Good luck.
