That's not very good to hear.

But if you're going to get pepper spray or mace or something like that, please, please take some formal instruction in how to use it and also in self-defense in general. I know from the forestry people I work with that many people end up shooting themselves instead of whatever is attacking them (in their case: bears), and that's quite counter productive! Self-defense will also make you feel a lot more confident and give you means to fight back if the circumstances require it, whether on your bike or elsewhere.

Peace. Thinking of you.
