Solved a thorny problem.

I ride my mountain bike on state forest trails in Pennsylvania. My biggest problem comes from thorns on the trails puncturing tiny holes in my tires. Stan's NoTubes keeps me moving by sealing the tires while I'm out in the mountains without having to stop and install a tube. I generally dislike sealant because I find it messy, so I don't use it on my gravel or road bikes since I don't get many flats on them. However, I find it a must on my mountain bike, and Stan's has always worked great to stop thorn punctures.
