Unloaded bikes laying flat on the ground take up a great deal of room, are a hazard to walk around, and are getting their pedal bearings filled with dirt. If touring bikes are laid on the ground, the bags soon become quite dirty and half of the equipment is unavailable unless the cyclist stands the bike back up. A picnic table can be used by only two people if it also has to also support their bicycles. I visited a campground for cyclists in Wisconsin that lacked so much as a tree to lean a bike against. Evidently, cyclists were supposed to stay up all night to hold their bikes off of the ground.
Cyclists have to get water or other fluids frequently.
The just-mentioned campground lacked any water, even though the fees were high. Day trippers usually carry a single bottle of water which can be emptied in much less than an hour during hot weather, yet on many bikeways, there is more than an hour's cycling between water sources. Along with needing to drink frequently, cyclists need to pee fairly often, a fact that is usually ignored. I sometimes wonder if the greater numbers of male cyclists is simply due to the fact that we find it easier for us to pee where there are absolutely no facilities. Along much of the East Coast and in New England, I found extremely few public businesses that sold food and drink which provided a rest room.
