I get a bunch of magazines, but there are two that I read pretty thoroughly, National Dragster, but I get frustrated with their lack of Top Sportsman/Top Dragster divisional coverage, and Speedway Illustrated.
Dick Berggren's SI has good racing coverage, and good technical articles. More than a few of my new racing tools and parts are a result of their technical coverage.
I do like Car and Driver's humor.
As for internet mags, I wish I could subscribe to a service that e mails me articles that I am interested in. I could have them routed to a folder in my e mail in box, and even when I'm stuck in the airplane I could go through the unread articles.
