I agree that at times, a MUP can be difficult to navigate. However, i am lucky enough that 1/2 of my ride can be done on one and USUALLY i have little to no other MUP traffic to deal with. Our MUP here is part of a large park and there are several paths to take. I used to in the afternoon ride on one particular section just to see all the MILF's, but i tired of the foot traffic so now i take one of the least used paths so i can keep moving. The paths are paved, in great shape and can be real fast---to me that sure beats hassling with cars. I Don't care where or who are riding, to me the most important thing is we are all riding--as long as your not a wobbler.
