That is a pretty Advanced skateboard from the mid 70s. I started out in 1963, on boards that were far more primitive.
I had a Hang Ten from Nash with steel wheels and by '68 I had an aluminum Pro Surfer with Chicago wheels and trucks.
But by 1975 I was riding a G&S warptail very similar to that Alva, and Fresno had an actual concrete skatepark.
That park lasted about two years before they got sued and tore it all down.
Nowadays I'm way too big to ride anything with less than 24 in wheelbase, and my favorite ride has a 33 in wheelbase. Needless to say I stay out of swimming pools and ditches. I am strictly into long distance Road riding.
I can do a little downhill but by the third stand-up slide my knees are too weak to continue.
If you want to do some real long distance cruising, and you need something stable because you are old, they have the Big Lazy. I have 2 for some reason.

This is basically a rolling water ski. LOL
