Cleave its interesting what you say about use of MUPs... when we first started the ride (also then limited to BCI, OCW and OCRR) it was on all the busy streets... I think we caused the Irvine PD (and some of us riders) some real anxiety. I believe this is a good compromise to get riders out, give them a chance to ride together in slow single file motion (which apparently is an art skill with so many riders) and then attack the streets. In the initial days we did cause some problems and issues with motorists - all people just trying to get home from home or pick up kids from soccer practice... the riders still get out there and I think the message is clear but I understand your concern.
