I learned "dirt" riding on a 20" BMX then left cycling altogether. Got married, had kids, then picked up a 24 inch BMX cruiser because I got bored watching my kids at the BMX track. Then I wanted to check out what all the fuzz is about MTB and got a cheap hardtail, then a better one... then onto burlier and burlier FS bikes.
I must say, when I go back to a BMX it's like I have to re-learn things all over again. The timing is definitely different... not necessarily harder, just different. I'm older (and probably lazier) and I do notice the jarring which I never did before.
