Yeah, 90 degrees at RR tracks has always worked for me before, but since it was my first ride on my new bike I figured discretion was the better part of valor.

Since that ride I've gone 160 miles or so on the new bike, and have a better feel for it and am a bit more comfortable with handling it on irregular stuff. I'm also used to the tires now. I switched from 38s on my hybrid commutermobile to 28s on my Waterford roadie. (actually, she's a cyclocross bike, but she's being a roadie right now)

Hopped on and off pavement edges several times yesterday. It does get better with practice!
