Really kind of you, Roy, to post that link for me. I have read it top-to-bottom. It was especially comforting to understand from the information that red pepper sprays such as the "Rail Guard" spray were effective 98 o/o of the time, with 92 being for Brown; 90 for Black; 100 o/o for Polar. Wind is a factor. The site even provided and handy diagram of how to angle the application.
Very, very nice of you to provide all that for me. Thank you, again.
P.S. It was even mentioned that the canisters are heat sensitive, so that leaving it on the dashboard would be a possible cause of a canister exploding since the contents are under pressure and, therefore, heat sensitive.
P.P.S. And, yes, I did notice

that no mention or recommendation was made concerning the (dubious) "wisdom"

of my

carrying an aluminum baseball bat with me,

also. (Even though I still will.) But as was pointed out when we were considering my garbage-curbing shenanigans, how would I manage all that equipment when under imminent attack?!

Oh well. I'll use the bat as a weed-whacker and walking stick. Who knows. But Roy, you came to the rescue! I was a bit dubious about such sprays and had my hopes mostly in the bat, but this information straightens that odd notion out, once and for all.
