Do ticks or other blood sucking bugs (mosquitoes, etc) show preference to certain people?

I'm currently on a hike and my friends have found about 1-3 ticks each while I've found 17 and an hour later another 15.  Is there a reason that ticks seem to 'love' me much more than my friends?

Yes.
Both ticks and mosquitoes tend to target people by detecting the CO2 they release from their bodies, so perhaps your metabolic rate is higher than average and produces more carbon dioxide. Blood type O is preferred over A and B for them as well. Additionally, it could be that you were walking in front of them and picking up more because you were leading the trail.
