On a semi regular basis I go on youtube and do some random searches by typing in some of my favourite subjects in the search. Being a car guy some of my favourites are:
-trucks, SUV's in deep snow *
-Snow plowing ...different North America provinces/states, Europe, etc.
-Heavy duty truck (6WD, 8WD) such as the Czech made Tatra, etc. ...going down primitive roads/ no roads/ hill climbing contests
-Motorcycle videos mostly on favourite vintage bikes...Matchless, Norton, BSA, Vincent, Velocette, Jawa, CZ, BMW, etc.
- farm tractors, old vintage HD trucks...Macks, Peterbilts, etc. in action....home made tractors which can be quite interesting
-cameras, light meter...how to's...
-drag races of vintage stock cars, Gassers, etc.
-driving tests (amateur mostly) of vintage vehicles....everything from '60's big sedans like Chevy 409's, 427, Ford Galaxie 427, Mopar 413, 426 wedge...'60's Volvos, V-Dubs, Sunbeam Tigers, Austin Healey 3000's, etc.
-Vintage Sports and sedan (saloon) car racing in England
* Snow and dealing with it has been a life long interest and past time...which comes by honestly, being a Canuck on the western prairies
Kind of esoteric interests...but these are some of the things I get a kick out of...
