It is good that you have found such pleasures in biking. In contrast to such places as Amsterdam biking is more or less tolerated than an integral part of the culture in most of the United States. Like yourself having had GBS was a part of life I could have done without. But some good came out of it when I became a founding member of the GBS/CIDP Foundation International so we could help others through their GBS 'adventure'. Happy biking. Joel Steinberg
