how far do you drive for classes?

For conformation (practice) its a 2-3 minute walk for me.

For agility (if we ever get in a class) its like 30 minutes.

Heh! I was just wondering this the other day on my way to class.

Our OB and Agility are at the same place (different nights though) about 15'ish mi away, but takes about 30 min door to door (it's a long, winding road with lots of speed traps) ... so we go the speed limit.

When I'm doing longer tracks (for tracking) I go out to a place nearby to my training facility... probably once a week, also. 

I'd say 10 min away ... you were spoiled!!! :o) 
 

Flyball is almost two hours away.  Needless to say we haven't made it there much.  But, they are starting an "eastern branch" that is going to be about 45 minutes to one hour away (depends on traffic).

Thankfully, my herding instructor is only 45 minutes away, no traffic, nice drive all through country back roads.  I used to go to someone 100 miles from where we lived.  Again though, it was an all-day thing, and I only went a couple times a month, until the last few months before he passed away and I was going a couple times a week to help out and whatnot (ah, the days of $1/gallon gas!).

I have, and will, drive six to nine hours for a good herding clinic.  But, since we've moved, I'm amazingly close to a ton of great options now - I rarely have to drive longer than three hours for anything now.  Four hours tops, which puts me in Northern VA/MD where they have tons of events all year.  The Jack Knox clinic the first of April, for instance, is a short three hour trip even though it's in SOUTHERN Maryland (lol). 

It was an unexpected bonus of moving out here from where we were, even though it felt like we were moving further out into the middle of nowhere.  In reality, we are now more central than before - we're in easy striking distance of Richmond, Lynchburg, Roanoke, Western VA, the Chesapeake River area, the NC Triangle, and the "Triad."

 An  hour to an hour and a  half, depending on where I go.  The only closer ones are the ones I teach, so no benefit to me as a student!
