I don't walk before sun up (that would be appropriate temperature wise) and I watch for them closely.
My big worry all the time is Sam, my dog. Every time we see one we have a teaching moment and he seems to be really good at avoiding them.
You had to know I couldn't go all weekend with out dumping a picture of Sam in here didn't you? What can I say?
Good thing this is a smart doggo! Nobody would want the poor thing gettiin' a taste of vemon.
