Although some protists (such as certain red, brown, or green algae) are multicellular and macroscopic, most protists are unicellular and microscopic, traditionally classed as either protozoans (primitive animals) or algae (primitive plants).NVIRONMENTS. Protists, in general, live in salt-or fresh-water, in soil, or in the bodies of other animals. Most slime molds live in the shade, as on rocks, leaves, or rotting tree trunks. Most euglenids live in freshwater.
1 Free or low-cost overnight RV camping is possible in some areas.  As a tryout or an alternative to buying, renting an RV can cost $50-$90 a night for a simple pop-up tent camper, or $150-$350 a night plus 35 60 cents a mile for a luxurious Class A motorhome.
Family Camping. Family campsites accommodate up to 8 people. They are developed campsites with amenities that vary from park to park, and may include fire pits or fire rings, picnic tables, showers, a water supply, and a cleared area for your tent. Each campground has a limit on the consecutive number of nights a camper may stay. Once this consecutive night limit has been reached, the campground must be vacated, and no one in the party may return to camp in the same park for 48 hours. A parent or guardian must accompany youths under 18 years of age.
