Being a Brit, see the name? When I travel in Ireland, the British Isles, Europe, I rent a car. I know the average American is petrified of traffic Islands, (roundabout's) and driving on the left! and would sooner go on bus tours.
Fight the urge, get a mid sized diesel 4 door, standard shift, cheap, fun, GPS a must. My Wife is the passenger, gets treated like royalty (same as here) open doors, stay on her side. I have been know to cause damage to threats to my Lady.
Do not remember what I paid for my "City Stick" from Cold Steel? I think it was expensive, I have had it for years. In England my Liverpool Accent is reason to pause! We have this reputation.
Watch body language, men tend to spread their legs to exert force, that same upswing with your cane is an attention getter. Miss my Glock 19 in Europe, wear it every day in Florida.
Cold-steel-city stick, stay with the fiber, or Aluminum head. Stainless is too heavy. Gets you on the plane first, the white beard helps.
Hang an old canvas bag up to practice on.
When carrying a straight cane, do not lean it up, they fall. 511 pants, lots of pockets, every one wears multi pocket pants, and vests in Europe.
Carry cash, same notes in same pockets. Change in front left. If you carry a folding knife, keep it hidden! I opened mine to cut a string for a Lady in a Newspaper shop, she just about collapsed.
