I hit the freeway on my 11th ride out, w/ a little over 400 miles of riding experience on surface streets. During those first 400 miles I gradually bumped up my top speed until I was doing 60-65 mph on expressways. When I finally hit the freeway for the first time, I exited on the next ramp, got back on and rode longer. It was great. I had been wearing ear plugs and felt fine with freeway speed by then. The wind blast at freeway speed was the biggest surprise.
