Nah, wouldn't go 80ft on a blaster. I'd find a way to get across it though. I had a really cool bridge that we built, but now we have so much traffic through our back yard. Somebody tried to take a tractor across it and it collapsed and has been falling apart since.
Hey Gus, on your offer: Can I bring a bulldozer?
Brad, jumping just takes time. I've never been hurt while riding. I've cased some doubles, rolled down some hills, but nothing too bad. Just take your time and make sure you're comfortable. I just keep making the jumps a little bigger until I can handle them. Never back out!!! I don't do anything big and am not a stunt guy. If you fall off, don't get tense, keep lose. I've never broken any bones and hope to keep it that way. Knock on wood.
