I think in here someplace is the overall issue...
Before bikes there were a lot of people on MUPs, most well behaved, some clueless, and others down right jerks.... All that said we all fell under the same motive power, we were all powered 100% by our own muscle. So now the people listed above are separated from the human power group to an assisted power group. Now an additional game is being played on the same field, and its getting crowded.
