Ups and downs. Most advancement is within first 5 years.
Pros: not stuck in a cubicle. can be physically demanding.
Cons: inclement weather, very little room for true advancement, mostly lateral moves
Get jobs on PDA, drive to work area. Repeat. Direct supervisors are great, co-workers helpful. Hardest part is dealing with the inclement weather and 24/7 work/oncall schedule. Best part is working outside and interacting with different people on a daily basis.
