I have traveled ~45 mins each way for physical therapy for my son.

Right now we see a specialist at a teaching hospital (pediatric orthopedist) and while it's not a regular appointment, it is a big chunk of time to drive to/from every time. We allow 1.5 hrs to get there because we never know how traffic will be, then we have to find parking, etc.

It's a blessing to live in a large metropolitan area where we have these options!
