I have no reason to not get another Rocket, that would be my 1st choice. The fly in the ointment is the wifey thinking tryke, that way she can ride along, which creates its own set of potential problems

. I am thinking a low mileage used R3 would still be the best, or just pop for a unsold new one. Either way I think I would come out OK.
As to the group riding, I totally agree with the comments. I raised the spacing issue a few times on this ride, I ended up getting stung. The smart move would be to do no more of these, or just ride separate of the group and arrive at the destinations a wee bit late, but safe. I am waiting for the helmet and the rest of my baggage to arrive in a bit as I want to see the helmet. I just might post a pix if it looks as bad as I was told.
