Am I being rude?

Strangers dont usually walk onto property and wander down your driveway without being invited were I live, unless they have criminal intentions.
My driveway fits one car in front of the garage, so its easy to look into garage and see what's in there....why i mostly keep the door shut......
Im into landscaping my property, I plant a lot of flowers and fall is for planting bulbs and putting in mums
When im out there, folks walking by stop often and compliment, maybe a short friendly conversation.
Im flattered and dont mind....Same with the old car but anyone I dont know stepping foot in the garage is a no-no and im vocal about that
