Elementary school. Walking and riding my bike (Huffy!) to school. Do kids still do that?
Arcades in the 70's and up to the mid 80's.
Being able to play pong at home on my TV!! (Odyssey 500 <-still have it w/ box!)
The first handheld video games.
Playing Atari 2600's and Intellivisions in the stores.
Finally getting an Atari 2600 ('81). Bro and I lived Atari 2600's (still have it w/ box).
When we had Godfathers Pizza (early 80's, the real Godfathers, not the gas station crap now).
When Star Wars Ep 4-6 and Indy Jones came out.
Going to PCB, Florida for summer vacations.
Finally getting cable!
MTV in the early to mid 80's.
Awesome 80's music.
No hip hop. Very little rap.
Finally getting a VCR!
My first BMX bike you couldn't buy at a dept. store (20" GT). Riding to the 7-11 to play Dragon's Lair, etc. Riding around the entire city with friends. Less worries of getting attacked.
Riding friend's motorcycles (dirt bikes).
My go-cart.
Going to the park for our ball games.
Commodore 64's, 300 baud modems (and running it at 400!), hundreds of 5.25" floppies of games, BBS's. Being able to finally get a second floppy drive ruled with Fast Hackem (I can still hum the music for it).
Finally getting my Amiga 500 (after a long anticipation period), that put my bud's PC to shame. Hundreds of 3.5" floppies of games. RAM expansion, extra floppy. Hard drive? Phfft.
All the 'first things' with the chicks.
Drinking for the first time.
Wanting an Iroc Z.
Getting my first car, a '78 Camaro

, in '87. Working on it, hot rodding it, putting money in it.
First concerts.
Headbanger's Ball.
College (Jr. High and High School sucked other than rolling and causing other destruction, and drinking).
Getting pilot's licenses/ratings.
Dance clubs.
It's all gone downhill from there.
Plus all the usual stuff...sports, fishing, running around the neighborhood, wiffleball, sledding, fireworks, friend's parent w/ hidden pron, causing trouble.
And:
When my parents were younger and all my grandparents were alive.
When I was younger with less responsibility, worries, and problems.
Before all my friends got married.
And:
Less bling bling. Pants worn to the waist. No stupid extra large chrome car wheels. Fewer thugs and gangs. Parents gave their kids more guidance. Kids obeyed more. Everyone spoke English.
