Leaking air What valve is this??

B,

They lock together only one way. If you don't do it correctly the ramp won't stay together.

Yeah, I've driven too far a few times but since the slope on both ends is so gentle it is really no problem normally. That gentle slope is another nice thing about these blocks but it also means you need a bunch of them.

You can use a big block of wood on the plastic block if you absolutely have to stop. I've done that when going too far would be a hazard.  

   OK, thanks.  That sounds like good news, should be easier than plain "block with a ramp" wood drive-up blocks.

   I have a set of these.  I was camped at an event a few months ago.  Somebody next to me drove off and left a set on the ground.  I went to the camp office and asked if they'd get in touch with the owner but they said "oh, we can't do that ... no, we won't take them".  So I took them home and contacted the organizers of the event and they sent out a notice but couldn't find the owners.  I'd be happy to get them back to the real owners but after a couple of years, I guess I can use them.
